GRI MM-400 Rare Earth Mighy Magnet, 3/8" Diameter 1/8" L, Nickel Plated (Min Order Qty of 10)

Solve thin-window and retrofit installation headaches with the George Risk Industries Rare Earth Mighty Mag MM-400 magnetic contact magnet. Designed specifically for security and surveillance applications, this low-profile contact magnet measures just 3/8" in diameter and under 1/8" (0.1") in height, so installers can mount reliable sensors without drilling into delicate vinyl frames. The rare-earth alloy provides exceptional magnetic strength in a much smaller footprint, improving gap performance while remaining discreet. Nickel plating protects against chipping and corrosion, ensuring consistent operation for monitoring and access control systems. The MM-400’s surface-mount, hybrid installation lets you use the included screws, double-stick tape, or adhesive—reducing install time and rework on retrofit jobs. Packaged by George Risk Industries for professional installers, this contact magnet is ideal for residential and commercial intrusion detection, door/window monitoring, and bespoke security projects. Minimum order quantity applies (10 per bag).
