Solution for Double-Leaf Door Systems

DORMA recessed bolts allow for the locking and unlocking of the passive door panel in a double-leaf system. Users can unlock the active panel with a quick, sharp hand motion, which simultaneously opens the lock of the passive panel, allowing it to be opened. This system automatically re-locks as soon as the active and passive panels close – no special action or additional activity is required to lock the system.

Reliable Function and Minimal Installation Effort

Thanks to its easy application, the HZ 43-F does not require any additional bolting. The adjustable and flexible sliding bolt restriction only needs a milled hole for the door latch bolt counter and a hole for the bolt slider – no need to break or remove any part of the door panel. Its two-part design allows for easy compensation of installation tolerances, ensuring the maximum stabilization of the door system.

Application Areas

The HZ 43-F is suitable for installation on the top or bottom of wooden door panels and metal doors and can be used, for example, with DORMA automatic operators and door coordinators. The HZ 43-F recessed bolt is approved for use in fire and smoke doors, subject to certification for the related door.
