GRI 150RS12B Recessed 1/2" Short Switch Set, Standard Gap 1/2", Brown

Ensure reliable perimeter protection with the George Risk Industries 150RS12B recessed magnetic contact — engineered for professional security, surveillance, and monitoring applications. This 1/2-inch recessed mount contact delivers a flush, tamper-resistant solution ideal for hollow core doors and vinyl- or aluminum-clad windows. The wider 1/2-inch diameter gives installers extra working room for wiring, End-of-Line (EOL) resistors or connectors, reducing installation time and post-install adjustments.

Built for installers, the 150RS12B snaps into place with a secure collar for a clean finish and supports either 12-inch leads or screw terminal connections to suit hybrid installation needs. With a standard 1/2-inch gap and Form A (N.O.) contact, it pairs with a range of GRI magnets to resolve tight or challenging mounting situations. Manufactured in the USA and backed by a lifetime limited warranty, this magnetic contact provides dependable performance for alarm panels, access control, and building monitoring systems.
