Overview
For secure, professional perimeter protection, the George Risk Industries recessed magnetic contact delivers reliable door and window monitoring in commercial and residential security systems. The GRI 140T-12-B magnetic contact set is engineered for concealed installations — the 3/4" switch bore eases wiring and servicing while the 3/8" magnet allows offset placement in thick frames. With SPDT (Form C) contacts and a 0.5" standard gap, this contact set provides consistent performance for intrusion detection, access control and surveillance integration. Hermetically sealed contacts and plated components minimize sticking or freezing, improving uptime in varied environments. Installers appreciate the press-fit, screw terminal or leaded termination options and the availability of longer leads or jacketed cable for flexible wiring runs. Designed for wooden or aluminum frames and backed by a limited lifetime warranty, the 140T-12-B is ideal for retail, office, healthcare and multi-family housing security projects.
