All doors, including interior and exterior, sliding and swinging, cabinetry doors, and more, use door latches as closing mechanisms. Doors can be opened and closed in a regulated manner with the help of latches, which also provide a secure connection. The door latch is a mechanical fastener that attaches two (or more) surfaces or objects while allowing for their normal separation. Read More…

Door Latches Manufacturers List
A latch on the opposite mounting surface often latches onto another piece of hardware. These mechanisms are also utilized in several home products and the auto sector for automobile doors and compartments. Latches are mechanical and, in certain situations, electro-mechanical devices that enable the temporary connecting of moving parts and, when triggered, enable the parts to separate from one another. This engaged piece of hardware may be referred to as a keeper or a strike, depending on the type and design of the latch.
Latches are fasteners holding closed doors, panels, and other surfaces. But not all latches are created equal, and the design of a latch is largely determined by the application, different actuation techniques, holding and locking preferences, and mounting techniques.
Types of Door Latches
Tubular latches, one of the most popular door latch types, are also called mortice latches.
By turning the handle or knob, the door will open or close. Homeowners most frequently use this internal door latch when discussing internal door latches. The same fundamental idea and design are present in a normal tubular latch, constructed using higher-quality materials. Double-sprung and heavy-sprung tube latches are the sturdiest and most resilient variations of this type of door latch.
The sliding or rotating bolt is secured when it travels behind the stable component. Then, the two pieces are fastened on securing surfaces, such as doors and frames.
The two primary bolt latches are the spring bolt and the deadbolt. A spring clip holds a spring bolt in place. The spring snaps into a locked position when it is released after being squeezed to unlock the bolt. When closed, this kind of door typically locks itself. Deadbolts lack a mechanism that loads springs. Instead, a key or a knob is used to lock or unlock the door. Of the two types of bolts, deadbolts are the more secure option, especially if the lock contains a deadbolt plunger. The smaller plunger adjacent to the deadbolt's function is to keep the lock from being picked or "jimmied" open.
Hook and Eye Latches
The majority of gates have hook and eye latching. These latches are easy to use and efficient, especially when used outside. As a result, these latches are also frequently called "barn door hooks." This latch is installed using two distinct parts, just like other latches.
First, the gate itself has an attachment holding the hook. The frame is next given an eye. The gate will be kept firmly secured when the hook is inserted into the eye. The installation procedure is simple because of how simple these latches are.
Rim latches are frequently utilized inside. This style of external door latch resembles flat or tubular latches with knob handles in many aspects. However, these latches are less secure than mortised door latches, incorporated within the door frame, because they are positioned outside the door.
Magnetic and Electromagnetic Door Latches
A ferromagnetic striking plate and a permanent magnet are the two components of magnetic door latches, commonly referred to as door catches. They are employed to offer a practical latching for furniture doors or low-traffic, light-duty doors.
Similar in operation, electromagnetic latches need a power source to function. The magnet locks the door when it is energized, bonding to the frame. The switch is used to de-energize the magnet before granting access.
Applications of Door Latches
Trailers and Cargo Containers
On trailers and cargo containers, door latches and gaskets are widely employed for several purposes. Depending on how much force is needed to hold them shut, door latches can be fastened to the corners or along one side.
Door latches can keep electronic circuit boards in place during production. In addition, certain parts within machines, like the locking mechanism for an engine's camshaft, fasten bulky parts to their shafts like gears or power takeoffs. They are also ideal for locking equipment composed of brilliant chromate and zinc alloy.
A standard door latch consists of two knobs on the inside and outer sides, a latching mechanism, and a locking mechanism.
Advantages of Door Latches
- They use simple mechanisms for door closing or opening.
- Depending on the application, they can be used on either side of the door.
- They keep intruders away.
Disadvantages of Door Latches
- The security mechanism of the door latches can be bypassed.
- They are expensive.
