Product Description

The LCN SEM7810E100AL is a 1-inch magnet extension designed for use with LCN electromagnetic door hold-open and door control systems. This small hardware component extends the reach of the door magnet assembly, allowing proper alignment between the electromagnetic armature and the door-mounted or wall-mounted magnet. It ships as a single unit and is finished in 689 Aluminum, a satin aluminum finish that coordinates with standard commercial door hardware.
