Electric locks and strikes

BLOCK-OUT with push button - with dead-bolt - Adjustable backset from 50 to 80 mm

The BLOCK-OUT electric locks with push button are suitable for inside and outside doors and pedestrian gates, and are interchangeable with the V97 locks (maintaining the old striker) and with the most common already installed electric locks. The manually operated dead-bolt ensures lock closing regardless of the electric impulse. The characteristics and finish make them ideal for wooden or metal doors and gates, even in surroundings subject to considerable temperature ranges.
