Exposed to rain, dust, salt air, chemicals, or heavy use? The GAI-Tronics 255-003YLLDSK is the tough, no-nonsense yellow weatherproof enclosure designed to shield a standard wall-mount telephone (like GAI-Tronics 2500 series or compatible models) from the elements while keeping it accessible and functional year after year.

This non-metallic, corrosion-resistant box delivers full NEMA 4X protection—sealed against powerful water jets, total dust ingress, and corrosive environments—making it a smart, economical choice for outdoor or harsh indoor installations. Perfect for industrial plants, oil & gas facilities, wastewater treatment sites, construction yards, university campuses, public parks, emergency call stations, loading docks, or any Texas outdoor spot where standard phones would quickly fail. The bright yellow color boosts visibility for safety, while the included lock and spring-loaded door ensure secure access without constant fiddling. Inside, a built-in RJ11 jack and #630 mounting plate make hooking up your phone quick and clean—no custom wiring headaches.
