Fixing a squeaky door hinge manufacturer can be one of those items on your honey-do list that gets put off time and time again because you’re simply not sure how to make the squeaking stop. If this doesn’t do the trick, you’ll need to move into something a little more complex — not to worry — it’s much simpler than just about any other repair you can think of!
　　How to Fix Squeaking Door Hinges with Pliers and Aerosol Lubricating Oil
　　Using a pair of narrow or needle-nosed pliers, remove the hinge pins of each hinge. You can do this one hinge at a time or remove all hinge pins at once and remove the door, setting it carefully against a wall. Obviously, if this is a large exterior door, you’ll want to do one hinge at a time so you don’t have to remove the whole door. Once you have chosen which route you’ll take, place the pliers on the top of the hinge, to move the hinge pin back and forth until it is loose enough to pull up and out with the pliers or your hands.
　　Cleaning Hinge Pins With Steel Wool and Sandpaper
　　Next, you will use some steel wool to aggressively scrub the pin: this process cleans the pin while also removing any points on the hinge that may have spurs (little splinter-like points created by wear and tear that could also be the cause of squeaking). By cleaning the pin, you can do because you are actively removing dust, grime, dirt, or even sand and other gritty debris that could be the cause of a creaking door. After you finish your aggressive cleaning with steel wool, dry it by hand and let it sit for 10 to 20 minutes so it is completely dry before you add any aerosol or other lubricants. While the hinge is out, you can also do your best with a rag to clean the hinge itself — you won’t use the steel wool here because if you were to slip it would cause a scratch to the finish or paint on your door. Try to run something through the hinge so it also gets a good cleansing to remove any debris that will still cause a squeak even when the newly cleaned pin is back in place. If you feel the squeaking is caused by friction between the pin and the hinge, use fine-grit sandpaper to file the hinge pin. This will remove any rust that’s creating resistance between the pin and hinge while also making it a tad smaller, which also lessens friction.
　　Replacing and Lubricating the Pin and Hinge
　　Before you place the pin back inside the hinge, lubricate it with either an aerosol lubricant door grease, machine oil, or even greaseless lubricant if you’re fearful an aerosol grease may contain chemicals that could harm the finish or paint on your door. Now you’re ready to put the pin back in, simply put it in place and push it down, using the gentle tap of a hammer or the butt of your pliers to make sure the pin is all the way in. Repeat this process on all three hinges and your door will be swinging and squeak-free — you can do this once every 12 months or so to clean the hinges and pins so squeaking sounds never return.

　　Tilt and turn windows come with several benefits over double hung windows. The first thing that you’ll notice is a major positive impact to your energy bill as these windows score high on energy efficiency. They are also easier to open, clean, and maintain. They can open completely or tilt open to let in some fresh air.
　　Although tilt and turn windows support great ventilation, they also have air seals and gaskets which allow your building to maintain the right temperatures, negate drafts, and minimize the cold that comes from being close to a window in the winter months. You will save money on energy and experience superior soundproofing that will give your building a special sense of peace.
　　Tilt and turn windows can fill the entire opening with no dividers blocking your view. For buildings in Landmark districts or where an historic appearance is desired, there are now tilt and turn windows available that look like double hung windows but operate differently.
　　REPLACING WINDOWS MAY NOT BE THE SOLUTION FOR YOU
　　While we are on the topic of replacing windows, it’s important to realize that not all older windows must be replaced. It is a common trend to knock out the old windows in a newly acquired building and insert new ones. However, it is sometimes better to salvage these old windows, restore them, and reinstall them. While many people are convinced that newer is better, several elements of older windows make them superior to new ones.
　　Original windows can have superior longevity, contribute to the character of the building, and tend to be made from materials that are beneficial for painting, staining, and milling. While they might not be as energy-efficient, sometimes there is a net loss to the environment for replacing them.
　　There are options available for window restoration such as vacuum insulated glass, special coatings and gasketing that can drastically improve the performance of historic windows.
　　The best window option for your building can be determined through a window study which takes all the factors of an individual building into account and will help you take the proper course of action to meet your needs. We can provide proper details for a watertight and airtight installation which is critical for window performance.

　　Finding the correct offset for exterior shutter hardware certainly can be daunting. But, with a little practice you’ll be well on your way to hanging your shutters with an offset that’s just right!
　　What is Hinge Offset and why is it needed?
　　Hinge Offset is the counterbalance needed for a shutter or door to easily swing open and close, clearing any obstacles such as a deep fitted window frame or trim mouldings. With a larger window hinge manufacturer offset a larger swing (also referred to as “throw”) is created making the shutter protrude, or kick out, further away from the pivot point of the hinge. Knowing which hinge offset you will need is just a matter of finding the amount of throw needed.
　　Hardware Basics
　　Hinges are comprised of two parts.view of pintles and straps for exterior shutter hinges
　　Exterior strap hinges and the “L” type straps (also called “New York style hinges”) shown here on the right consist of a strap and a pintle. In this picture the pintle is on the left and the strap is on the right. The strap mounts to the shutter’s back face and the pintle mounts to the building. Most, if not all shutter and door hinges, are made to be able to separated for installation, as well as general maintenance, hence the term “Lift off Hinge or Loose Pin Hinge”.
　　Measuring Offsets for Plate Mount Strap Type Hinges
　　example of pintle offset
　　Pintle offset is measured from the base, to the center of the pintle, or pin. When measuring pintle offset sometimes the plate will be included and sometimes not. The measurement will be close enough to measure either way. In this picture I did not incude measuring the plate portion of the pintle that the tape measure is seated on. See how the measurement is one and a half inches ( 1-1/2″ ) to the center of this pintle pin shown to the right?
　　Measuring the offset on the strap is similar to measuring the pintle offset. Just measure to the center of the knuckle, the hinge joint, less the strap thickness.

　　Tilt & turn windows are an innovative window solution. They open in two distinct ways; tilting in from the top for ventilation and swinging fully open for access to the window’s exterior. They are a popular choice in high rise installations but are also used in regular two storey and single storey properties.
　　Tilt & turn windows security capacity
　　Tilt & turn windows are a popular window choice for homeowners across the UK. One question we regular receive, however, from customers considering tilt and turn windows for their home is: ‘Are tilt & turn windows secure?’ Because of their wide opening capacity, people are often concerned about their security capacity. These concerns are, however, completely unnecessary.
　　Tilt and turn windows are in fact one of the most secure window styles. They are often viewed by glazing specialists as more secure than other window styles because to ensure that the window functions properly during both opening actions, extremely strong hardware and multi-point locking systems must be used. This enhances the tilt and turn window’s security rather than reducing it, making tilt & turn windows one of the safest windows available today.
　　Safe and secure tilt & turn windows
　　We install a range of high performing uPVC and aluminium tilt and turn windows. All our tilt and turn windows are fitted with high security locking systems as standard. We have installed tilt & turn windows on a wide variety of properties from multi-residency high rise buildings to two storey terraced homes and even single level bungalows.

　　Door hardware otherwise known as ironmongery, is more than just handles and knobs, especially when looking at external doors. Apart from the aesthetics, the most important factors are security and durability, other desired factors are functionality and weather resistance. Let’s look closer at the types of ironmongery being used and examples of available products, starting with door hinge manufacturer.
　　Door Hinges
　　Unless it’s a pivot door, every external door must have hinges installed to swing open and close. There are literally hundreds of types of hinges available in the market. How to find the right one?
　　small cabinet hinge for light loads – not suitable for normal/heavy doors
　　First of all, external doors require minimum 3 hinges per door leaf – there is a requirement for all escape route doors to have a minimum of 3 hinges. Also, external doors are usually heavy and actually require 3 hinges to take the weight, but on larger, heavier, thicker doors it may even require 4 hinges per leaf, it all depends on the quality of hinge and its maximum load against the weight of the door. On top of that, we should always allow for extra weight for unforeseen circumstances like external forces, uneven wear, additional ironmongery such as door closers (use of door closers can add even up to 75% to the calculated door mass) etc. and it all becomes rather confusing and difficult to calculate, so let’s simplify –
　　Rule 1: use 3 good quality hinges per door leaf unless it’s an oversized door
　　(54mm thick or more, 1100mm wide or more, 2400mm high or more), in which case it’s best to get a door or hardware specialist to calculate if 3 hinges are enough or 4 are needed.
　　One of the most important factors is the material the hinges are made of. Cheaper hinges are usually made of brass with a polished chrome or satin chrome coating – these should not be used on external doors as they are prone to corrosion and could snap under a heavy load. On exterior doors, only solid stainless steel hinges should be used and stainless steel as a material comes in a variety of grades based on a number of physical properties like density, corrosion resistance, thermal expansion etc.
　　Rule 2: for external doors use hinges minimum of grade 9 and grade 13 is recommended.
　　Hinge Mechanism
　　Apart from unusual circumstances the only 2 types of hinges to consider are butt hinges and concealed hinges. Butt hinges have 2 identical halves connected by a round knuckle making a rotary movement. It looks and works a little bit a like a butterfly. Butt hinges have a variety of sub types each having some subtle differences, the most common are:
　　washered hinge – not recommended for external/heavy doors
　　washered hinges – Thinner knuckle with movement made on metal washers. Not recommended for external applications.
　　ball bearing hinges – thicker knuckle with ball bearing mechanism. Recommended inexpensive, high durability and low maintenance hinge.
　　thrust bearing hinges – thicker knuckle with thrust bearing mechanism. High end butt hinge suitable for very heavy loads, highest durability, no maintenance but significantly higher cost.
　　Apart from butt hinges there are also concealed hinges, which are becoming very popular nowadays. They are completely invisible from either side of the door, as they are recessed into the frame and the door. This is of course desired from an aesthetics point of view but there are certain disadvantages to bear in mind:
　　Concealed hinges require specific custom-made frames (non-rebated). The most common in the UK rebated external door frames will not work.
　　Concealed hinges require recessing deep into the frame and the door.
　　Most are not suitable for high traffic areas and their maximum load is lower than in butt hinges.
　　They are the most expensive hinges for external doors.
　　Rule 3 – use ball bearing butt hinges as default for most domestic and commercial scenarios, alternatively concealed hinges or thrust bearing hinges for more specific requirements.
　　Door hinges & Security
　　The majority of external doors in the UK are opening inwards. This requires hinges (or the knuckle) to be positioned inside the building behind a rebated frame, which means the hinges are protected from tampering from outside. The only way to break through the hinges is by forced entry. Outward opening doors have hinges accessible from the outside which makes them an easy target for tampering. Concealed hinges are not accessible from either side which makes them the most secure, however their high cost and the need for a special frame may be an obstacle and for the majority it will not be necessary. There are also ball bearing butt hinges with special, hidden security studs preventing forced entry. It’s a combination of a hinge and a door bolt, where both leaves of a hinge, lock together – see picture below. This prevents doors from being lifted out and even doors opening outwards cannot be attacked from outside. With a minimum of 3 hinges required per door, they provide 3 extra locking points on the hinged edge. These hinges are inexpensive with cost around 15-20% higher compared to a regular ball bearing butt hinge and we highly recommended them.

　　For commercial doors determining the door swing direction, also known as door handing, is important for ordering the proper hardware, making sure the door is prepped correctly, and ensuring that the space protected by the door is functional.
　　Door Handing for Single Openings:
　　1: Begin by standing on the outside (secure side), facing the door.
　　The secure side is typically the side where you would insert the key to gain access to the building or a room. For doors without a keyed lock, stand on the side of the door and window hinge manufacturer where you would typically use a key to gain access to the building or room.
　　2: While still standing on the outside (secure side), determine the location of the hinges.
　　• If the hinges are located on the left side of the door it is “hinged on the left”
　　• If the hinges are on the right side of the door, it is “hinged on the right”
　　3: Continue to stand on the outside (secure side), to indicate the direction the door swings.
　　• If a door pulls toward you, it is a reverse handed door.
　　• If the door pushes away from you, it is not a reverse handed door.
　　4: Combine steps 1, 2, and 3 to come up with one of the four handings listed below.
　　Left Hand: The door is hinged on the left and the door pushes away from you.
　　Left Hand Reverse: The door is hinged on the left, and the door pulls towards you.
　　Right Hand: The door is hinged on the right and the door pushes away from you.
　　Right Hand Reverse: The door is hinged on the right, and the door pulls toward you.
　　Door Handing for Double Doors that Swing/Open in the Same Direction:
　　1. Begin by standing on the outside (secure side), facing the doors.
　　The secure side is typically the side where you would insert the key to gain access to the building or a room. For doors without a keyed lock, stand on the side of the doors where you would typically use a key to gain access to the building or room.
　　2. While still standing on the secure side of the doors, determine if there is an active leaf.
　　A “leaf” is referring to a single door panel, for double doors there are two “leaves.”
　　Active Leaf: The active leaf typically contains the locking hardware, or it is the leaf that is generally used most often. It is also the leaf that needs to be opened first before the other leaf will open.
　　Inactive Leaf: Typically, this is the leaf that does not have operable hardware on the secure side, and it usually will remain secure until the active leaf is opened.
　　2: While still standing on the outside (secure side), determine the location of the hinges on the active leaf.
　　• If the hinges are located on the left side of the active leaf it is “hinged on the left.”
　　• If the hinges are on the right side of the active leaf, it is “hinged on the right.”
　　3: Continue to stand on the outside (secure side), to indicate the direction of the door swing.
　　• If the active leaf pulls toward you, then it is reverse active.
　　• If the active leaf pushes away from you, then it is not reverse active.
　　4: Combine steps 1, 2, and 3 to come up with one of the four double door handings below.
　　Left Hand Active: The active door is hinged on the left and the door pushes away from you.
　　Left Hand Reverse Active: The active door is hinged on the left, and the door pulls toward you.
　　Right Hand Active: The active door is hinged are on the right and the door pushes away from you.
　　Right Hand Reverse Active: The active door is hinged on the right and the door pulls toward you.
　　Door Handing for Double Egress Door Openings:
　　Double egress doors are double doors that swing in opposite directions which can help control traffic. Their intent is to allow free access and egress (entering and exiting) from both directions using the door leaf that pushes away from you. To ensure traffic flows only from the push direction, the pull side of each door typically does not have any trim.
　　Each leaf has an opposite “secure” side, which means both door leaves need to be noted for handing.
　　When facing the doors, look at the leaf that pulls/swings towards you (pull side). Both doors are usually handed in the direction that pulls toward you because they often use panic hardware or fire exit hardware, and that type of hardware is only used on reverse swing doors.

　　If you want to customize your door even further, you can choose a custom hinge that is best for the door weight and application.
　　Special applications and door types require different hinges. These may be called full mortise, half mortise, full surface, half surface and many other specialty door hinge manufacturer.
　　For example, there are Full Mortise style Bearing Hinges that are exclusively manufactured for high frequency and/or heavy wood or metal doors. Typical applications would find this hinge type in schools, hospitals or public buildings with high traffic.
　　When thinking about custom hinges, you should consider the following:
　　How will the door be used? Will it need to be a fully revolving door or a 180-degree door, for example?
　　How much will it cost to design a special hinge for thickness and size?
　　What size of hinge do you need? If you have heavy-duty, large doors that are load-bearing or have additional equipment that hangs on the door, then you may need a different hinge with a custom thickness.
　　How big and thick is the door?
　　How will you install the hinges? There are four main ways to install hinges including full mortise, half mortise, full surface, or half surface.
　　What style and finish do you prefer?
　　What material is needed for your industrial application? If you need rust-resistant hinges, then you’ll pick stainless steel. Brass, iron, and bronze are also available.
　　Will you need to remove the door or is it fixed?
　　Manufacturing a Commercial Hinge
　　Hinge manufacturing refers to the production process. Both hinges and latches are typically made by the same manufacturer, and they begin the process the same way.
　　To start off, the chosen metal material for the hinge is melted. Once it’s at the right temperature, the manufacturer puts it through several machining processes.
　　After the hinge is created, it’s put through secondary processes to perfect the thickness, size, and shape. These processes include painting, coating, polishing, plating, rust-proofing, smoothing, or galvanization. These are determined based on the application for the door hinge.
　　The manufacturer must consider several things when choosing what product mix to manufacture. These include budget, required production volume, design complexity, and required production speed.
　　Custom Hinge Design
　　When designing a hinge, manufacturers begin with the main components which are typically the leaves, knuckles, and hinge pin.
　　The leaves are plates that fold outward, and they are held together by a knuckle or hollow joint. The knuckle is joined to the hinge by a pin.
　　When installed, the leaves are attached to the separate surfaces that will be held together. Screw holes are drilled into the leaf so that they can be fastened to the door and frame.
　　Standard Fabrication
　　The parts of a door hinge are quite simple to fabricate. These include:
　　Leaf
　　This is also called the wing of the hinge, and it’s the flat piece of the hardware that’s screwed into the frame and door.
　　Pin
　　This long pin slides into the knuckle holding the two leaves together. If you pull the pin out, you can remove the door from the frame. Some doors need removable hinges so that they can easily be lifted and removed.
　　Knuckle
　　The middle part of the hinge is called the knuckle, which is a cylindrical case that allows the leaves to rotate causing the door to move.
　　Sleeves
　　These are the cylindrical pieces that create the knuckle and hold the pin together.
　　Special Application Hinges
　　There are a variety of hinges depending on the application and industry. Hinges may require galvanized steel or other material depending on the temperature and chemical exposure around the door.
　　These have a wide range of uses for standard use, high traffic and extra heavy doors.
　　Example: A welded hinge installation is best when you need to suspend a heavy door. These are capable of holding doors of extreme weights. Bank vaults and blast doors typically use these types of hinges.
　　Unique Hinges
　　For certain industries, warehouses and other businesses in heavy-duty applications need their own unique types of concealed and durable application hinges. A few unique hinge examples include:
　　Wrapping Up: What Type of Hinge is Right for Your Door?
　　There are all kinds of hinges out there for commercial applications. Though butt hinges are the most common and can be used for many door types, specialty hinges can offer concealment or specialty hinges can offer solutions for uncommon applications.
　　So, whether you need an interior or exterior hinge, you must first look at the door weight, any chemical resistances and use application that meets or exceeds the specification required. The right hinge will be able to handle the load and resist corrosion due to exposure to elements, which typically means a non-corrosive material. That’s why it’s best to work with a specification consultant to get your specs right.
　　However, even the strongest hinge cannot help a door that is not sufficient for your commercial building. You need the right door and hinge to withstand the test of time. Good luck and always consult with a professional first before starting your project.

　　windows that don’t close properly, hinge screws that are loose, hinges that are squeaky – these are just some of the many window installation issues caused by hinges. But you can actually remedy these problems on your own and get that window operating smoothly.
　　Here are 4 common window hinge installation problems and their quick fixes:
　　1. window not closing tightly. When this happens, your window hinge manufacturer may not be aligned. You can solve this by making sure that the window jamb is in the same plane.
　　2. Uneven window. One of the causes of an uneven window is a window hinge that is out of plumb. If this is the case, use a level and make sure that the window hinge is plumb.
　　3. Hinge screw is loose. When you feel that a hinge screw is loose, you should check the hole it is attached to, which may be too big. To solve this issue, you can use a longer screw that will reach into solid wood behind the hole. Alternatively, you can glue small pieces of toothpick or a similar material into the hole so the screw will fit better.
　　4. Hinge is squeaky. Squeaky hinges can be solved by lubricating the hinges with oil. You can do this by inserting a nail under the hinge pin, pushing it up, and then adding a drop of oil over the pin.
　　The quality of window and window products is enhanced by hardware which seals against the elements, making the products easy to operate, while at the same time discouraging burglars.
　　The tilt andturn hardware fittings feature the flexibility of two opening positions. The sash will swing inward - casement style - when opened in the turn position. Alternatively, hinges at the bottom and a tilting arm at the top allow it to open inward at the top like a hopper window (tilt). Both actions are activated by the turn of the handle, a smooth operation which controls all the mechanics within the frame.
　　The hardware around the window has several locking pins all around, which lock the sash into the frame to provide multi-point metal-to-metal security locking. This means that the energy saved through double or triple glazing is not lost through a draughty frame.
　　There are great benefits with the tilt and turn operation. Ample fresh air can pass into the room in the tilt position. This position also acts as a safety precaution that prevents small children from climbing through the window, and with an optional child safety lock makes it compliant with the new Building Code. The fully opened inward turn position makes life easy when cleaning windows.

　　If you have ever looked at the lock on your front door, you may have noticed that not all locks are the same. There are many types of locks available around the world but for now, let’s just focus on two of them, mortise locks and tubular locks- building hardware manufacturer (not to be mistaken for cylindrical locks). Why these two? Well, they are the two most common types of residential locks in the US and when installed, they can look almost exactly the same. Some manufacturers make the same style of lock in both mortise and tubular versions. This can make it tricky to identify what you need if you’re replacing a lock and it is a valuable piece of information to have during the process.
　　These locks require your door to be prepared or “drilled” in two very different ways. Because of this difference it’s important to know which type of lock you have. It’s never fun to buy something that doesn’t fit correctly and knowing this information will help narrow your focus while shopping. It is possible to convert a door from one type of lock to the other, but it requires a skilled professional and can be a costly endeavor.
　　Modern mortise locks have been around for over a hundred years and get their name from the rectangular shaped pocket that is mortised in the edge of the door that receives the lock body. They are a tried and true product that is engineered to last and if taken care of properly, can last a lifetime. Most standard exterior mortise locks require a 5-6 inch tall mortise pocket (depth varies with backset) for installation.
　　Tubular locks have been around since the start of the 1900’s and get their name from the tube shaped hole that is drilled into the edge of the door that the lock fits into. These locks were designed to reduce the cost of manufacturing and the labor-intensive preparation needed on a door. Each lock requires two cylindrical shaped bores – one into the edge of the door and one through the face of the door. The standard for these are a 1 inch diameter edge bore and a 2-1/8 inch diameter face bore.
　　So, if they can look basically the same when installed, then how can you tell them apart? You can always identify one from the other by looking at the edge of your door or more importantly, the latch face. Because the mortise lock encompasses all the locking functions into a single lock body you will see one long face plate, most commonly about 8 inches on an exterior door and 4-6 inches on an interior door. This face plate will include the latch as well as the deadbolt if there is one. Tubular locks break these two functions apart into two individual components, an independent latch and an independent deadbolt. For this reason, when identifying a tubular lockset, you’ll see an independent face plate for each function. A small face plate for the latch and a separate face plate for the deadbolt. These typically measure 2-1/4 inches tall.
　　If you’re building a new home or replacing a door, either lock can work for you and there are a few features/benefits of each that can help you decided.
　　Mortise locks, while more expensive, typically have a longer life span as more of their components can be serviced. They are commonly seen on the exterior doors of high end homes.
　　Tubular locks are less expensive but many have to be replaced entirely if they fail.
　　Both can be used in lever by lever, knob by knob, and handle set by lever/knob applications
　　Mortise locks are always handed (right hand vs left hand). With tubular locks, it depends on the manufacturer.
　　Both can have emergency egress – a feature that, with a single action, will unlock the door and open a door to allow for exit in the case of emergency.
　　For mortise locks, this feature is built into the lock and you can still use a sectional trim on your entry set.
　　For tubular entry sets, an emergency egress mechanism must be used on the inside of the door requiring a longer escutcheon plate.
　　Exterior mortise locks commonly have toggles/stops which allow for the outside trim to be locked without a key
　　On locks with emergency egress, this is done automatically when the deadbolt is projected. It is important to note that the outside trim will remain locked until manually unlocked with the toggles/stops. It does not unlock as part of the emergency egress function. This is due to fire regulations.
　　Tubular locks are available with a key in knob/lever function with or without emergency egress and can be a great option for storage areas or mechanical rooms where a lock is desired and a deadbolt is not needed.
　　When using a tubular lock, a separate deadbolt is needed when a secure door is called for. (The deadbolt is where your door’s security comes from, not the latch)
　　Mortise locks can have a latch, deadbolt, toggles/stop, and auxiliary latch or any combination thereof in one lock body.
　　Most tubular deadbolts have a single hardened steel pin in the bolt to prevent people from sawing through the bolt. Mortise lock deadbolts have two of these pins.
　　Interior mortise locks are smaller in size and are available with or without skeleton keys. These are great when replacing or matching old hardware.
