A door latch is one of the most common internal mechanisms for closing a door. This particular type of ironmongery is usually'morticed' into the door frame, with a spring or other mechanism returning it to its protruded state whenever the knob or lever is not being turned. Most of these are tubular latches, so we will explore their design and function, as well as how to correctly measure a spindle hole for a new handle set.
A typical tubular latch consists of a steel, rectangular tube that can contain a number of different latch mechanisms. The most straightforward type has a spring-loaded 'tongue' that retracts into the latch body to open the door, and then pushes out and retracts when the knob or lever is being turned. This design is commonly found on furniture doors, and it is an easy way to keep a door closed without requiring a key to unlock it.
Door latches can be used on both right-handed and left-handed doors, but there are a few factors to consider when choosing the correct latch for a door. The first consideration is the 'backset measurement', which refers to the distance between the edge of the door and the center of the keyhole's case. Most doors have a case depth of 64 mm or 76 mm, and these measurements should be taken into account when purchasing latch hardware.
It's also important to know that the latch spindle must fit through the thickness of the door and whatever trim is in place, so it should be long enough to accommodate this. Often, it will be easiest to simply replace an existing latch with the same model, and to check that the latch spindle is long enough before installing.
A door lock latch is the mechanism that closes a door. It consists of a spring bolt that is angled off toward the edge of the strike plate (a flat metal plate fastened to the doorjamb). When the door handle is turned to open the door, the angled bolt is pulled down until it engages with the strike plate and snaps into place, locking the door.
If you’re experiencing a problem with your door latch, lubricating it can help. However, if your latch isn’t retracting when you turn the handle, there could be a more serious problem. To troubleshoot the issue, you can try some common methods like using a credit card or using a screwdriver to wiggle it.
If lubrication doesn’t work, you might have a misalignment or looseness of the door latch bolt and strike plate. You can fix these problems by tightening the door hinge screws and by adjusting the strike plate. You can also replace the latch cylinder if necessary.
Different Types of Door Latches
The door latch is the main mechanism that secures your doors and keeps them closed. While most door latches are similar in terms of functionality, there are different types that consumers can choose from. Understanding the different types will make it easy for you to pick the right one for your doors. There are two main categories of door latches: those that are internally embedded in doors and those that are externally installed. Each category has its own unique features and functions.
Tubular Latch
The tubular latch is the most common type of door latch. This latch comprises of a rectangular steel casing tube that houses a spring-loaded follower and a latch bolt or ‘tongue’ at the end. The tongue retracts to open the door, and springs back when the door is closed. This type of latch can be used in both out-swinging and in-swinging doors. It also comes in various variants, from the economy tubular latch to double-sprung and heavy-sprung varieties.
Iron Latch
The iron latch is a popular choice among homeowners due to its durability and longevity. It can also be customised with different colours and finishes to match your interior décor. Unlike brass latches, iron ones don’t require much maintenance and can last for years.
Bronze Latch
The bronze latch is a good option for homeowners who want a more colonial and traditional look. It has a beautiful sheen to it and can complement almost any style of interiors. It is also durable and rust-resistant. Moreover, it is cheaper than other latches.
