Every day, you come into contact with different types of latches because they are used everywhere, from the magnets that keep the cupboard pane to the automotive industry.

But what are they actually, and what types exist in the market? This guide will go over the various types that are available in the market and provide brief explanations of how they work. Continue reading to learn more.

What is a door latch?

They are a type of fastening tool that is commonly used to keep gates closed. They may take the shape of a sliding bolt to stop the gate from swinging open or a hook to keep it closed during sliding and swinging motions. Additionally, they have a locking system to keep one side from releasing them. Modern versions are constructed with electrical and electronic components, high-tech lock systems, and electrically activated releases.

Functionality of door latch

This product’s function is to maintain the entrance’s closed state. It is made to be easily closed in one direction by pushing on the entrance. It is intended to stop unauthorized entry into the entryway. The lock does not prevent them from moving. It should be noted. By doing this, the entryway can be locked before being shut. It provides the user with a certain level of security and privacy, for instance, when using the restroom.

Door latch vs door locks.

The main distinction between locks and latches for entrances is that the former requires a key to open the gate, whereas the latter does not. As the name suggests, the former ensures that your gate is closed, whereas the latter allows you to close the gate but ensures it is not locked. Both of them serve the same purpose: to provide security for you.

The type of locks or latches you have installed on your entrance will determine the security level both offer. The effectiveness of them is in preventing intruders from entering your homes or property can vary depending on whether they are made of durable materials.

Types of latches commonly used in India.

Let’s take a look at each latch type in a detailed manner.

• Chain latch

  

  It is another basic type that is a popular choice among homeowners. It provides slightly more security than the other options. These are combined with other locking mechanisms. The installation of two components is required, just like with other types. To begin, a track is attached to the gates themselves. After that, the chain is attached to the frame. The entrance can be secured by inserting the chain’s end into the track’s slot.

• Rim Latch

  

  They must be installed in combination with a rim knob and are mounted on the face of the door. This type of arrangement is common in older-style cottages.

  It has a latch that can be opened by turning a knob and a key that can lock the entryway from both sides and shoot into a keep attached to the rim of the frame. Instead of a key, they have a button that is pressed across with the finger to secure the gate from one side.

• Barrel Bolt

  

  This is yet another piece of frequently used hardware that solves the problem of entrance shifting because of crooked bolts. They offer a quick and simple installation process that only needs to be done once, and they work with both interior and exterior applications like gates and windows. It comes in a range of sizes and coatings.

• Roller bolt Latch

  

  You can easily pull your entrance open when you place them in an entryway. The roller mechanism itself can be adjusted, enabling you to fine-tune the amount of force required to pull the entryway open. When the lever is closed, the entryway is securely held shut. This is commonly found in wardrobes.

• Sliding Bolt Latch

  

  It makes use of a lock or metal bolt that can be used to lock down a gate. To unlock the entryway, all you have to do is slide the metal bolt to one side. The rod can once more be used to fasten this to close the gate. This enables homeowners to increase the security of their entrances.

• Flat Latch

  

  However, these are more frequently used with heavy-duty doors since they don’t require a locking mechanism. It can be found in most interior gates that don’t require extra security. A handle is used to control these as well. When looking through them, you’ll discover a range of sizes, components, and finishes to meet your requirements.

• Tubular Latch

  

  It is a simple and direct closing mechanism frequently used on interior gates without a lock. It is an evolution from a mortice lock that has been shrunk to make installation easier and necessitate less door drilling and cutting. It is a crucial component of contemporary ironmongery and is very widely used.

• Hook & Eye Latch

  

  These are simple and efficient, particularly for exterior use. Like other types, it is installed with two separate elements.

  To begin, an attachment clutching the hook is connected to the gate. The frame is then fitted with an eye. The entrance is secured in place when the hook is inserted into the eye. The installation process is simple due to its basic nature.

• Swing Bar Latch

  

  Many homeowners are now using this modern lock to replace older ones because it provides an additional layer of security. It is attached to the door frame and lets homeowners open their entrance slightly. Compared to other types, these are somewhat more difficult to open.

• Gravity Latch

  

  These have a self-closing mechanism that operates due to gravity. The lock will slide into position and keep the gate closed when you swing it shut. These are typically mounted on an inside area of the fence. A striker will be attached to the gate. It will be mounted on the frame to house the lock mechanism. The striker will self-close when it comes into contact with the device while closing the gate.

• Ring Latch

  

  Because of this functionality, these are a popular choice among homeowners, particularly for backyard gates.

  Despite being mounted on one side of the gate, the lock can be opened from either side by turning a ring-shaped handle. Because of this compatibility, these can also be locked with padlocks for added security.

• Thumb Latch

  

  These are a hybrid of gravity and ring type. A metal plate and a device known as a thumb depressor are typically found on a gate’s exterior. While a locking lever and lock mechanism will be installed on the inside. When you press the thumb depressor, the lever on the opposite side of the gate opens.

• Cam Latch

  

  It comprises a fastener and an attached arm, or cam, which rotates to lock. They are spherical in shape and have a metal tube with a hole in one side that aids in positioning the bolt when it is inserted.

  These are commonly used to prevent unauthorized access in vending machines, file cabinets, desks, and display cases. They are mostly invisible in fully constructed cabinets.

• Toggle Latches

  

  It is distinguished by having a part that is constantly under tension. They work well in applications where strong closing forces are needed to keep seals in place and prevent leaks, dust infiltration, and water ingress. They are also made to stop the lock from accidentally being released. Equipment control panels and electronic enclosures are two examples of applications for this product.

• Door Hasp

  

  It is a straightforward lock that relies on padlocks for additional security. It is quite simple to install and use. It consists of a strap and a staple. The strap is made of a metal plate with a slot on one end that fits over the staple. It is hinged on the other side, enabling the strap to swing while being fastened to a surface. A pin is inserted into the staple’s loop to secure the strap, or a padlock is used if the application calls for more security.
