MSL Mortise locks ROLLTRIBLOC 1857 H

On both sides, a push button is installed. Additionally, a roller bolt with roller pins is attached. When the door closes, the roller pins are moved upwards into the locking position in the strike plate located in the door frame by pressing the button. This pulls the door leaf against the door frame. A turn of the key in the locking direction extends the main bolt. When closing, the roller pins move downwards into the open position in the strike plate through a button press. A turn of the key in the opening direction retracts the main bolt.

With button operation: locking block, bolt extension of 20 mm, single turn, with Delrin latch, bolt made of hardened special steel, automatic button reset, combinable with roller bolts, lower locking bolt can be rotated 180° (replacement for ROLLTRIBLOC 1840), without change.

Without roller bolt, without locking plates, without strike plates.
