The SHL-1200 shearlocks are part of our family of electronic locking devices. These units are ideal for traditional single action doors (one way opening), or for double action doors (swing-through) providing the door closers are of a good standard. They provide discreet high security locking with the minimum of fuss. The shearlocks have a holding force up to 1200kg, and include lock status monitoring as standard. Additionally, they will accept free voltage of 12 to 48vdc. A full range of accessories are available to enable the shearlocks to be fitted to most doors, even glass.
