Types of Door Latches Door Lock Latch

Door latches are mechanical components used to join moving parts, enabling them to be actuated and then separated.There are a wide variety of latch types and designs. They are categorized by their method of actuation, holding style, and mounting.

A knob climbed door latch, also known as a rotary or cylinder lock, uses a pin affixed to the handle socket to keep the handle open when the door is shut. When the knob is turned, it transforms the cylinder and rotates the pin to release the latch bolt. The pin is spring-loaded most of the time, so it snaps back into a locked position when the doorknob is released.

Some knob climbed latches use levers instead of knobs, which improves aesthetics and enhances grip. Others are designed to be opened with a push, allowing them to be opened quickly and effortlessly by people who need to exit the door in emergencies. These are often called panic bars.

Mortise door latches, which are incorporated into the frame of the door, offer greater security than latches that are mounted on the surface of the door. They are primarily used on commercial and institutional buildings. Magnetic latches are a popular option for low-traffic or light-duty doors. They consist of a non-magnetic body with bar magnets inside that contact a ferromagnetic strike plate mounted on the doorframe and jamb.

A door lock latch is a mechanical fastener that connects two or more parts of hardware while allowing them to separate normally. They are used in several home products, such as sliding and swinging doors, cabinetry, and door handles. They are also a part of many automotive doors and compartments. There are a wide variety of latches available, with differences in design and functionality. The choice of a particular latch depends on the application, different actuation techniques, holding and locking preferences, and mounting techniques.

A turn latch is a common type of latch that features a knob on one side and a bolt (the tenon) on the other. When the knob is turned, the cylinder engages a series of spring-loaded pins on each of its surfaces. The uneven pins keep the cylinder from turning until the key is inserted, which allows the cylinder to be opened.door lock latch

Other latches feature a lever instead of a knob, which improves appearance and makes it easier to open the door. Some levers are designed to meld with certain architectural styles. There are also latches that hold large bars, known as panic bars. These latches are designed to be easily opened by pushing them in an emergency, such as during a fire or a natural disaster.

Latches are made from metals or other materials that can be enhanced by secondary processes such as finishing and coating. These techniques create a bright, shiny finish that protects the hardware from corrosion and enhances its aesthetics. They are also available in different thicknesses and finishes to suit specific applications.
