Electric lock for overhead doors

STEP 50 is a high quality electric lock for industrial doors. The electrically locked doors are conveniently and securely controlled via, for example, an access control system.


The lock is specially designed to withstand harsh environments such as garages and industrial premises.


STEP 50 uses no power upon the locking, and only opens with power that can be disconnected immediately once the door leaves its closed position. The door status locked/unlocked and open/closed is detected by two microswitches. If the lock is connected to an alarm system, the alarm will be activated if the gate door is forced to open.

STEP 50 resists forces of 1000 kg.
