LINEAR WINDOW LOCKING DRIVE
Category:

Unlike the FRA 11-BSY+, this window locking drive is not mounted on the sash. Instead, it can be integrated into the window profile, so it is no longer visible from outside. Manual emergency unlocking is possible at any time. It can also be used on windows without perimeter hardware, in a latch version.
