Orbit Industries RB75-5 4 Inch Round Weatherproof Box

Product Description

The Orbit Industries RB75-5 is a 4-inch round weatherproof electrical outlet box designed for outdoor and damp-location wiring applications. Constructed from die cast aluminum with a gray powder coat finish, this box delivers corrosion resistance suited to exterior installations. It measures 4 inches in diameter and 1.5 inches in depth, with five 3/4-inch conduit hubs that allow flexible routing of conduit entries. Licensed electricians and experienced installers use this box for weatherproof receptacle, switch, and fixture installations where code requires a listed weatherproof enclosure.

The RB75-5 is well suited for residential and light commercial outdoor wiring scenarios, including exterior wall-mounted receptacles, landscape lighting feeds, and conduit-connected weatherproof switch locations. The five pre-punched 3/4-inch hubs accommodate multiple conduit entry configurations, making it adaptable to both rigid metal conduit and intermediate metallic conduit installations. Each unit ships individually shrink wrapped with a barcode for easy jobsite inventory management.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes for weatherproof and wet-location enclosures. De-energize the circuit at the breaker panel and verify voltage absence with a meter before any wiring work. Ensure all unused conduit hubs are properly plugged to maintain the weatherproof rating of the assembly. Use only listed weatherproof covers and fittings rated for the intended location classification.
