GRI 4473-BL 3/4" Recessed Wood, Aluminum, Vinyl Switch Set

Protect doors and windows with a durable, low-profile magnetic contact engineered for professional security applications. The George Risk Industries 4473-BL magnetic contact is a recessed switch set designed for wood, aluminum and vinyl frames, offering a clean appearance while delivering reliable perimeter detection for access control, alarm and surveillance systems. Its press-to-fit 3/4" switch paired with a 3/8" magnet reduces install time and labor, while hermetic sealing and plated contacts guard against environmental damage, sticking and freezing to maintain consistent monitoring performance. With a 0.5" standard gap and N.O. closed-loop (Form A) contact, the 4473-BL integrates easily with wired security panels and monitoring equipment. US-made and backed by a lifetime limited warranty, this rugged magnetic contact is ideal for new construction, retrofits or any application where dependable door/window sensing is required. For tailored installations, longer leads, zip cord or jacketed cable are available on request.
