George Risk Industries (GRI) is a longstanding U.S. manufacturer of magnetic reed switch contacts, magnet assemblies, proximity and pushbutton switches, keycaps/keyboards and a broad set of accessories for intrusion, access and environmental sensing. GRI products are widely used by alarm installers, facilities maintenance teams, OEMs and contractors for door and window contacts, overhead/garage door monitoring, pool/panic alarms, and industrial proximity sensing where reliable magnetic switching is required.
Important attributes to confirm on Safsale listings or manufacturer spec sheets include gap size (standard/WG/XWG), electrical configuration (open/closed, SPDT/DPDT), built-in end-of-line resistor values, lead length or terminal type, mounting style and color/finish.
GRI reed contacts and magnets are used in residential alarm zones, commercial door/window monitoring, warehouse and dock door monitoring, safe/manhole protection, and OEM equipment for machine access detection. Many models are specified for outdoor and cold-temperature applications where hermetic sealing and plated contacts are required.
Safsale’s GRI manufacturer page aggregates product images, SKU examples, short specs and downloadable datasheets to make it easier to compare gap size, configuration and resistor options, and to collect multiple SKUs for a single installation type prior to ordering.
Maintain a short list of commonly used part numbers, inspect legacy contacts for stamped part numbers or magnet case styles, and verify EOL resistor values when required by the alarm panel.
Tema básico: For security and facilities procurement, GRI provides a broad, field-proven set of magnetic contacts, magnets and accessories. Use Safsale’s listing details, images and spec attachments to confirm the exact GRI part number and variant before purchase.
