Drop bolt locking mechanism with multi-point locking (standard)
The drop bolt locking mechanism is used as standard and provides secure multi-point locking. The number of hooks depends on grille height, with min. 3 pieces.
The locking bar is raised using the handle and lowered using the hooks located in the front rail. A profile cylinder lock is used to prevent unauthorised operation of the handle and thereby raising of the locking bar. Backset 45 mm.
