Secure windows without compromising the frame — the George Risk Industries N5425 recessed contact set provides a low-profile, installer-friendly solution for intrusion detection and monitoring. Designed for modern thin vinyl windows, the 3/8-inch recessed switch set uses an MM-400 rare earth magnet to maintain a reliable standard gap in closed-loop alarm circuits, giving you consistent contact performance for security and surveillance systems.
