This narow style centre lock is designed as a convenient way of locking roller shutter or garage doors. It is deliberately narrow enough to fit on the lathe in the body of the roller shutter rather than having to affix to the bottom rail bar.
The Ground Unit Complete comprises a ground socket with a spring loaded cap, a curtain eyelet and a bayonet eyelet. Whn used with the Tessi 85mm armoured lock this offers an effective way of locking roller shutter doors.
This key switch is 'momentary' which means that when you let go of the key the shutter stops opening or closing. It is designed to be surface mounted to the wall beside the shutter door which it is operating.
