Door latches are fasteners that keep doors, panels and other surfaces closed. They come in a variety of designs, materials and coatings to meet different needs.Common latch types include bolt, spring, slam and compression locks.
Material selection - Many types of door latches are made of metal. This includes carbon and stainless steel, as well as alloys such as copper and aluminum.These are durable, tough and can withstand high traffic. They're also available in a variety of colors, thicknesses and finishing processes to improve their aesthetics.Finishing options include painting and powder coating. These coatings can help prevent rusting and add corrosion resistance to a latch's finish.
Mounting type and installation procedures are another consideration. There are a few different mounting options, including flush-mount, mortised and surface-mounted.
Faceplate and backplate are also important aspects of door latches. A faceplate is a metal plate on the edge of the door that can protect the lock from wear and tear.A backplate is a metal plate that is installed between the faceplate and latch bore, the hole where your latch enters the door. This allows you to reposition the latch if it isn't in place properly.
A door lock latch is a key part of any door’s locking mechanism. The strike plate is a metal piece mounted to the door jamb that curves over the latch mechanism when it closes. As the latch hits the strike plate, it temporarily retracts the rounded end of the lock bolt until the knob or lever is turned, which releases the bolt and allows the door to open
Door lock Latches are typically finished with coatings to add corrosion resistance. Common finishing and coating processes include plating, painting, and powder coating.
Latches can be flush-mounted, mortised, or surface-mounted in architectural applications. Flush-mounted latches have both the latch and door surfaces on the same level, while mortise and surface-mounted latches are installed by screwing the assembly to the door’s surface and frame.
A door latch is a closing device used to keep doors shut. Designed to be controlled and secure, they are often used on residential and commercial buildings as well as in many industrial settings.
The most commonly found type of door latch is the bolt latch. This mechanism is activated by turning a knob or lever located on the exterior or interior side of the door.Other types include the spring latch and slam latch. These are essentially the same as the bolt latch but with a larger body that is able to resist more bending forces than the bolt.
Unlike the door latch, a spring latch is not retractable, instead it is pushed out of the door jamb by turning the knob or lever. The latch won’t disengage unless the door is locked, so it’s an excellent choice for high-traffic and heavy-use doors.
