This latch is designed for doors that are not equipped with pre-installed latches. It consists of a wall-mounted swivel bracket and a top-mounted locking arm, which can firmly secure the latch to the door body and effectively lock it in place during installation to prevent the door body from moving.

The reserved opening size of the latch is precisely 1 inch × 1 inch × 2.5 inches. If the size is larger than this specification, it may not be able to be installed successfully.
