Bolt locks for timber and steel doors
Our bolt locks have been specially developed for double-leaf door systems made of timber or steel. The bolt locks ensure reliable locking of the inactive leaf at the top and bottom. Automatic locking is provided by 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. Versions with motorized unlocking on the inactive leaf further expand the range of applications.
