ASEC Door Chain with External Cylinder

This Asec Door Chain with Cylinder is an innovative take on the traditional door chain design, featuring external key release and internal chain access. The chain body uses a simple push in engagement with a standard external rim cylinder which enables the chain to be disengaged externally with a key in emergency scenarios (ideal for people such as carers to gain access while the chain is on the door) and it can also be easily released using a push button. This particular model is supplied complete with a compatible external cylinder.
