GRI 180-12WG 180 Series 3/4" Steel Door Recessed Switch Set, Wide Gap, 10W, 200VDC, 0.40 Amp, Closed Loop, N/O, A, and U.L. 10C Fire Rated, White

Ensure dependable door monitoring for commercial and industrial steel doors with the George Risk Industries GRI 180-12WG recessed magnetic contact. Designed as a purpose-built magnetic contact for access control, intrusion detection and security monitoring, this 3/4" recessed switch set delivers reliable performance even on heavy-duty frames thanks to a wide gap capability (standard 0.75", over 1" on steel). The closed-loop N/O contact and 10W / 0.40A / 200VDC ratings make it easy to integrate with alarm panels, surveillance systems and building automation.

Built from steel with a self-locking, one-piece design and UL/ULC approvals — including a UL 10C fire rating — the 180-12WG minimizes service calls and complies with safety requirements. Standard 12" leads speed installation and eliminate extra labor for soldering or terminal work. Ideal for retrofits or new builds where dependable door supervision and low maintenance are priorities.
