GRI 81-12WG-BL 7/8" Steel Door Recessed Switch Set Wide Gap, Black

Deliver reliable, tamper-resistant door monitoring for commercial and industrial steel doors with the George Risk Industries 81-12WG-BL magnetic contact. Designed specifically for security and access control applications, this recessed switch set gives you consistent alarm and surveillance performance even where frames and doors have wider tolerances — the 0.5" standard gap handles misalignment without nuisance trips. Its 7/8" (0.9") steel, low-profile recessed mounting offers vandal resistance and a discreet footprint ideal for high-traffic entrances and retrofit projects. Integrated features like self-lock mounting and an End-of-Line (EOL) resistor streamline wiring and reduce installation time, helping contractors and integrators cut labor costs and minimize callbacks. Built for continuous monitoring in alarm systems and video surveillance environments, this magnetic contact pairs easily with standard control panels and access control hardware. Backed by a lifetime warranty, the GRI 81-12WG-BL is a cost-effective choice for long-term security infrastructure.
