Motor-driven bolt locks for timber and steel doors

Motor-driven bolt locks for timber and steel doors meet the highest requirements for security, convenience, and controllability. Thanks to their compact design, variable backset dimensions, and precise bolt technology, they are ideal for use on double-leaf doors – both in new buildings and for retrofitting.

The automatic locking of the inactive leaf provides maximum protection while maintaining high user convenience. Unlocking is performed electrically, e.g., via an access control system or a swing door operator.

The locks are certified according to EN 179 and EN 1125 for use in escape and rescue routes. In combination with monitoring contacts, panic functions, and electronic controls, motor-driven bolt locks offer a powerful solution for security-critical applications in public, commercial, and sensitive areas.
