George Risk Industries 180-12-G-IND 3/4 in Steel Door Switch Set

Provide a monitored door-status point on a 3/4 in steel door with a gray magnetic contact switch set built for physical-security applications. The contact assembly supports installations that need to report whether a protected steel door is in its normal closed position or has moved away from that position. Its gray finish helps maintain a consistent appearance where gray security hardware is already in use. George Risk Industries 180-12-G-IND is suited to door-monitoring circuits associated with intrusion detection, access-control monitoring, and other physical-security systems that accept a door contact input. Install the switch set at the monitored door location and connect it to the appropriate control or monitoring circuit for the site. The 3/4 in steel-door designation is the key fit criterion when matching this contact assembly to the door construction. This specific switch set is differentiated by its stated application for steel doors, its 3/4 in designation, and its gray color. Those details matter when replacing an existing door contact or standardizing visible security hardware around a facility. Select the unit where the monitored opening requires a steel-door contact assembly rather than a general-purpose contact intended for another mounting surface or door material.
