They are better suited for thin doors and can be put in without removing the frame or door.
A basic latch consists of the base and the bolt, both attached to a keeper. When the bolt is inserted into the keeper, it activates the latch and holds one end of the bolt to the door, and the other end to the keeper.

There are many rotary latches that are suitable for heavy and light duty applications. thekeylab.co.uk are made from different materials that include carbon steel and alloy steels. They are selected based on their formability and machinability. The materials are then forged or stamped to the desired shape in order to make the various latch parts. The parts are then reassembled to form a finished product.

Magnetic door latches are made up of an nonferromagnetic frame, bar magnets, and steel plates that concentrate the magnetic flux. They are then welded to the frame and door to ensure a secure lock under stress or in harsh conditions. The latches are available in lock and non-locking models, with the locking model that requires a key.
