GRI N2020-12 Series Rare Earth Might Mag Standard Gap Switch Set, Recessed, 2020-T-B with MM-400 Magnet, Closed Loop White

Protect sensitive vinyl and thin-frame windows while maintaining dependable perimeter security with the George Risk Industries Mighty Mag N2020-12 recessed magnetic contact. Designed for installers and security integrators, this compact rare-earth contact uses the MM-400 magnet to deliver a generous standard gap of approximately 3/4" (and up to 1" on wide-gap configurations), reducing the need for invasive drilling and speeding up installations. The recessed mount and low-profile magnet provide a discreet appearance ideal for surveillance, alarm systems, and access control projects. Built with nickel-plated protection and paired with GRI's press-to-fit contacts, the Mighty Mag offers consistent closed-loop performance for monitoring door and window openings. Hybrid mounting options — screws, double-stick tape, or adhesive — give you on-site flexibility, while compatibility with standard alarm panels simplifies integration. Choose the N2020-12 for professional-grade magnetic contact performance that minimizes installation risk and maximizes detection reliability. Add this Mighty Mag to your next security or monitoring installation to improve speed and reduce callback risk.
