Product Description

The THOMAS BETTS B1501SGR is a single-gang aluminum outlet box designed for electrical wiring installations requiring weather-resistant enclosure performance. Rated NEMA 3R, the box protects against rain, sleet, and external ice formation, making it suitable for outdoor and exposed locations. The rectangular aluminum body measures 4.5 inches in overall height, 2.5 inches in overall width, and 2 inches in overall depth. A powder-coated silver finish adds corrosion resistance.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit and verify absence of voltage before beginning work.
