Bolt locks for tubular frame doors
Our bolt locks for tubular frame doors have been specially developed for double-leaf door systems with narrow aluminium or steel profiles. Thanks to their compact design, variable backset dimensions and sophisticated mechanism, they are ideal for both new construction and retrofitting.
The bolt locks ensure reliable locking of the inactive leaf at the top and bottom. Automatic locking occurs via a suitable control lock when the door is closed, while unlocking is performed manually – either via a turn knob, a bar handle or a push bar. Variants with motorised unlocking on the inactive leaf further expand the range of applications.
Certified according to EN179 and EN1125, the locks provide standard-compliant safety in the event of an emergency. In combination with GU system components, they can be flexibly integrated into modern access and security solutions for commercial, administrative and educational buildings.

Emergency exit devices with lever handle or push plate for doors in escape routes
The EN 179 standard refers to emergency exit devices intended for use in buildings where it is expected that people familiar with the escape route can quickly and safely reach an exit in an emergency. These locking systems are designed to be easily opened in the event of an emergency. They require only a simple hand movement without the use of keys or similar aids. EN 179 specifies requirements for the design and performance of such systems to ensure their reliability and safety.
