Door slider

A door latch is a mechanism that is used to lock or secure a door, providing an additional level of security. It consists of a set of bolts or locks located along the entire length of the door, allowing it to be locked at multiple points. Depending on the model, the espagnolette can have different locking points, usually at the top, bottom and sides of the door.

The operation of an espagnolette is based on the synchronization of locking mechanisms through a single control element, such as a handle or key. In this way, in one move, the door can be locked in several places at once, making it more resistant to burglary attempts.
