Door Latches - Types and Uses in Different Materials

Appropriate selection of locking bolts according to the type of door and application

Crevices are locking mechanisms used primarily on double doors to secure one of the leaves. Their selection depends on the door material, the level of use, and the type of installation required.

Functioning of the locking mechanisms in double-leaf systems

The espagnolettes allow a leaf to be fixed by means of rods that extend towards the floor and the upper frame, maintaining stability and alignment in the structure.


Importance of the material in the system's performance

The type of door directly influences the durability of the latch, so it is important to select models compatible with wood, aluminum or metal.


Applications of espagnolette bolts on doors of different materials

The bolts adapt to multiple environments, from residences to commercial premises, depending on the type of door where they are installed.


Use on wooden doors for residences

On wooden doors, espagnolette bolts offer a firm and discreet closure, ideal for interior doors or double entrances.


Installation on aluminum and glass doors

In aluminum or glass systems, escutcheons designed for lighter structures are used, maintaining safety without affecting aesthetics.


Most commonly used types of bolts


• Mortise lock (concealed inside the door)
• Surface fault (externally installed)
• Manual bolt with rod
• Automatic lock
• Espagnolette bolt for metal or commercial doors
