GRI N20RS-12 Series Switch Set, MM-400 Rare Earth Magnet, Stubby Recessed, Closed Loop, Standard Gap, White (Min Order Qty of 10)

Designed for fast, non-invasive security installations, the George Risk Industries N20RS-12 magnetic contact delivers reliable door and window monitoring without drilling into thin vinyl frames. This contact magnet set features rare earth magnets in a recessed, stubby package with a low-profile less than 1/8 inch, enabling discreet placement on narrow sashes and minimizing damage risk. As a closed-loop magnetic contact, it provides consistent signaling for alarm panels, access control, and surveillance integrations. The nickel-plated finish protects against chipping and corrosion while the screw-mount form factor ensures secure, hybrid installation. Use the MM-600 magnet option with a standard gap switch to attain a wide-gap solution when needed. Made in the U.S. and sold in minimum quantities of 10, the N20RS-12 is ideal for retrofit projects, multi-unit deployments, and professional security installers seeking time-saving, durable components.
