The SHL1200 is a traditional shearlock. It is ideal for single action doors which always rest in the same position and include high quality door closers. The construction of the SHL1200 makes it suitable for both aluminium and wooden doors . Being very robust in construction and performance, this shearlock provides a holding force of up to 1200kg. Additionally, a varistor is built into the electronics, eliminating back-EMF and protecting sensitive controlling devices such as keypads and access control units.
