Door latches are mechanical devices used to secure doors and keep them closed. They consist of a movable component, typically a metal or plastic tongue or bolt, and a fixed strike plate or receiver that the tongue engages with when the door is closed. The latch mechanism is usually mounted on the edge of the door, while the strike plate is installed on the door frame.
When the door is closed, the tongue of the latch extends into the strike plate, preventing the door from opening unintentionally. The tongue can be retracted by operating a lever or doorknob, allowing for easy access Door latches provide a fundamental level of security, privacy, and convenience in residential, commercial, and industrial settings, making them an essential component of door hardware.
There are different types of door latches available, including:
A paddle latch is a type of latch that features a wide, flat handle or paddle on one side and a catch or strike plate on the other. When the paddle is pressed or pulled, the latch mechanism engages or disengages, securing or releasing the door or panel.
Also known as a push-to-close latch or compression latch, a swell latch is designed to secure doors, hatches, or compartments by applying pressure to compress a rubber or elastomeric gasket. When engaged, the latch creates a seal that provides a watertight or airtight closure.
A toggle latch, also called a draw latch or over-centre latch, consists of a pivotable metal lever or handle and a catch plate. The lever is operated by pulling or pushing it over-centre, which causes the latch to lock or unlock.
A tubular latch also referred to as draw latches or over-centre latches, consist of a pivotable metal lever or handle and a catch plate. The lever is operated by pulling or pushing it over-centre, which allows the latch to lock or unlock securely.
A compression latch utilizes a cam or lever mechanism to compress and create a tight seal between a door or panel and its frame. These latches provide high clamping force, ensuring a secure closure.
Door latches are composed of several components that work together to secure a door or access panel. These components can vary depending on the type of latch, but common elements include:
The latch body is the main housing of the latch mechanism, typically made of metal or durable plastic. It houses the internal components and provides the mounting point for the latch.
The striker plate is a metal plate mounted on the door frame or jamb that receives the latch bolt or tongue, securing the door in the closed position.
The latch bolt or door tongue is the part of the latch that extends from the latch body and engages with the striker plate to secure the door. It can be operated by a handle, knob, or other actuator.
The actuator is the mechanism that operates the door latch bolt. It can be a handle, knob, lever, toggle, or other device that triggers the locking and unlocking action.
Proper maintenance and care of door latches are crucial for ensuring the door or panel opens properly. Regular inspections and maintenance can prevent malfunctions, extend the lifespan of the latch, and ensure that doors remain securely closed when needed. Here are some key maintenance points:
Door latches are essential components in various industrial settings, providing secure closure and access control for equipment, enclosures, and access panels.
Industrial door latches are used in discrete manufacturing to secure access panels on machinery, control cabinets, and equipment enclosures, preventing unauthorised access and protecting sensitive components.
In process manufacturing, door latches are used to secure access points to process vessels, tanks, and control systems, ensuring safety and preventing accidental release of hazardous materials.
Door latches are crucial in energy and utility applications for securing access to electrical panels, switchgear, and other critical infrastructure, preventing unauthorised access and ensuring proper workplace safety.
In facilities and intralogistics, mechanical door latches are used to secure doors, gates, and access points in warehouses, distribution centres, and other facilities, controlling access and maintaining security.
Choosing the right door latch depends on several factors, including the type of door, the level of security required, and the environment in which it will be used.
