The Viro 8977 blockout electronic lock is designed for use on inside and outside doors as well as pedestrian gates. It has a double replaceable coil which distributes the load uniformly and ensures a long working life. This lock also features a solid brass nickel plated self-locking latch and a deadbolt which is manually operated ensuring the lock closes regardless of the electric impulse. When the deadbolt is thrown, the lock can only be open by key.
The ejector is separate from the latch to ensure the correct working of the lock even if there is vertical adjustment between the lock and the striker (caused by weather changes). Supplied with keys, strike and allen key for backset adjustments.
