Feataures and advantages: Effective protection against burglary: The locking mechanism of the window is locked via the lockable turn handle.It is no longer possible to release lockings from outside when the window pane is damaged or the frame drilled. The metal bolt engages in the robust locking socket with a throw of 18 mm.As a result, the window sash is protected from being lifted and forced open.With the lockable turn handle and the face fixed lock applied together,a great anti-burglary effect is achieved. Easy assembly ‚¬â€œ the face fixed lock is screwed on the sash under the turn handle.The locking socket is positioned on the frame and fixed with screws. The G.U face fixed lock can be retrofitted on tilt-turn and side hung sashes with 15 mm backset gear. The adaptation to various overlap thicknesses is effected with packings.
