GRI 2120-12WG 3/8" Press Fit Ribbed Recessed Switch Set, 1" Wide Gap, Closed Loop, N/O, A, White

Designed for dependable intrusion detection, the George Risk Industries GRI 2120-12WG recessed magnetic contact delivers a fast, reliable solution for door and window security. The unique 3/8" press-fit ribbed housing self-centers during installation and covers over-drilled holes, saving installers time and eliminating the need for adhesives. Built with flexible, crush-resistant ribs, the 2120 protects the reed switch from swelling wood and header shift — reducing false alarms and ongoing service calls. Rated for a 1" wide gap and configured as a closed-loop N/O contact, it supports common wired security and monitoring systems used in commercial and residential surveillance and access control deployments. Standard 12" leads simplify wiring, and the product's lifetime warranty gives long-term assurance for integrators and facility managers. Ideal for retrofits and new installs where a clean recessed mount, reliable operation, and low maintenance are priorities. Add the GRI 2120-12WG to your next security or surveillance project for a robust, installer-friendly magnetic contact solution.
