Description
Protect standard wall telephones from rain, corrosion, and tough outdoor conditions with the GAI-Tronics 255-003SK. This non-metallic NEMA 4X enclosure with spring door closure gives facilities managers and business owners a practical way to keep 2500-series phones working longer at pools, docks, dugouts, ships, garden centers, and similar sites.
For customers who need reliable outdoor or harsh-environment phone protection without moving to a fully sealed industrial telephone, the 255-003SK is a smart, data-backed choice. Its engineered plastic body resists corrosion, the latched door delivers Type 4X protection when closed, and the spring closure helps keep the door shut after use. Best suited for poolside, dockside, baseball dugouts, shipboard, and garden-center applications where a standard 2500-series wall phone needs lasting weather protection.
