Effeff door bolts largely owe their usability to thier compact size. These bolts are suitable for both private and public use. Thanks to the wide range of models, you can find the fitting one for doors from standard to glass doors.

Electric bolts are reliable accessories of the lock and strike. They are mostly used for specific requirements, e.g. with special doors (like swing or sliding doors), where they function as additional locking.

For door bolts with a built-in monitoring contact, the bolt status can be monitored, thus e.g. an equipment can only be started if the relevant door is locked.
