Things to Consider when Buying an Internal Door Latch

You can never underestimate the importance of security in your home. Interior door latches may seem like little additions but they hold significant importance in the grand scheme of things. A durable door latch ensures security and peace of mind. There’s also the fact that they offer aesthetic value.

For those who haven't installed door furniture before, finding the correct size internal door latch to purchase can be difficult due to the different sizes available. Internal door latches in the UK typically come in two styles and a variety of finishes.

Think About the Backest

The ‘backset' is a vital aspect to consider when choosing the right internal door latch size for your window. The backset serves as a gap running from the centre of the door handle to the edge of the door, or the point where the spindle can move through the door if you're replacing doors.

In the United Kingdom, carpenters usually use two backset sizes for housing purposes: 45mm and 57mm. When choosing a mortice internal door latch, you'll notice that the total length of the case is specified: 76mm (3 inches) and 63mm (2 ½ inches).

If you're installing door handles on new doors that haven't had latches before, the case measures at 57mm backset. It is generally favoured because it positions the handle slightly farther away from the door frame than the 63mm door latch. Therefore, it fits inside the centre of most regular size panel door edging.

The 57mm case backset door lock is preferred when installing doorknobs because it places the knob farther away from the door body. By doing so, it protects your palm from being trapped or scratched by the casing and handle of the door.

If you're changing existing interior door latches, make sure you choose the same size as the old ones. This way, you can avoid any form of obstructions from old wood shavings.

By extracting the original latch and measuring the lengths, you will determine the backset and total length. If the doorknob or lever is already in use and you don't want to change it, calculate from the door's edge to the centre of the handle.

Types of Door Latches

Each internal door latch has its unique shape and style that best suits different doors. Here at InternalDoors our extensive range of quality internal door latch types can fit every need.

Basic Tubular Latch

Each internal door latch we sell has a specific purpose and application. The most popular latch used in the United Kingdom is our basic tubular door latch.

Structural Tubular Latch

Structural interior door latches are the next level in terms of consistency and style. If you're installing new entryways, we highly recommend these particular door latches as they're a superior option.

They have two springs in the mechanism: one is a gentle contact spring that allows easy shutting of the door without any need to push the handle down. The other is a harder spring that gives the handle a very firm shutting motion.

They also come in a dark receptacle, also known as a splinter block that sits in the back of the flat striker plate and conceals the frame's timber. The best part is this type of tubular latch has an aesthetically pleasing appearance.

Smart Latch

Additionally, there’s the smart lock, which is a brilliant way to easily install an internal door latch without having to use a scraping tool. This latch is a popular favourite because it saves time and looks great. It goes well with the classic circular door handle collections.

Adjustable Latch

Our more flexible latches are the last type of internal door latch in the UK that we provide. From the 1980s to the mid-1990s, a firm named Weiser supplied house builders all over the world with tons of latches.

It was a one-of-a-kind device that was simple to install and all the installer had to do was rivet a hole that is about 45mm in the door. Then, they would insert the handle into the supplied internal door latch.

Unfortunately, production of the Weiser latches has ceased, and new knobs and interior door latches have been unavailable until now. This has necessitated the replacement of whole doors or the use of old knobs.

Our adjustable internal door latch type allows you to choose from a variety of contemporary levers and handles without having to hire a carpenter to install new doors. This will save you a lot of money in the long run.

Choosing the Right Tubular Latch for Your Door

The tubular door latch is the most common option to go with, especially in the UK. If you are a first-timer installing an internal door latch, the tubular latch is the way to go.

The tubular latch is a basic locking mechanism often used on doors that do not need a lock. The tubular latch is a smaller version of the mortice lock that can be installed with less difficulty and doesn’t require much cutting and hole boring to the door.

In short, it’s a staple of modern ironworking, and it's easy to see why. To make certain internal door latch sizes fit your gate, they are available in a variety of shapes, and combinations.

Typically, a latch-body made from mild steel with an abridged faceplate is used. Furthermore, a brass or steel tongue and an 8mm follower are also part of its mechanism. The cube-shaped hole through which the spindle connecting the doorknobs moves past the latch is known as the follower.

The faceplate and strike plate are most often provided with cube-shaped edges. Although, they are also available with circular edges. These are often used by manufacturers who use a machine to cut pre-made holes in the door. But for regular joes who use a shaping tool, the cubic edges are smoother!

Finishes for Tubular Door Latches

The faceplate and strike plates are available in a variety of colours, allowing the internal door latches to be properly aligned with your door hinges and handles. Electro Brass or Nickel Plated economy latches are the most popular and more affordable options.

Powder Coat Black, Polished Brass, Satin Steel, Polished Steel are among the finishes available on higher-quality latches.

Tubular Latch Sizes

According to industry standards, measurements for the sizes of the tubular latch are 152mm, 127mm, 102mm, 76mm and 64mm. These are the average dimensions of the internal door latch sizes. Note that each of these dimensions has its backset measurement.

As previously said, the backset serves as a space between the latch's faceplate and the follower's centre. It’s crucial because it determines where your knob will rest on the door's face. Backset sizes in the market are 130mm, 107mm, 82mm, 56mm, and 45mm. As a result, the following general rule applies:
