Lux Safety Hook (Brown)
Safety hook is a security system applied in winged systems (doors, windows, etc.). Two steel parts mounted on the casing with the wing eliminate the possibility of opening by stretching. Since the ends of the bolts are self-drilling, it is very easy to install.
It is applied to all kinds of doors, PVC windows and aluminum joinery. It can also be applied on steel doors and wooden doors.
It also prevents the doors and windows from sagging over time.
