Thomas Betts DIH3-2-LM Outlet Box Aluminum 1 Gang

Product Description

The THOMAS BETTS DIH3-2-LM is a single-gang aluminum outlet box designed for electrical installations requiring weather-resistant enclosure performance. Rated NEMA 3R, this rectangular box protects against rain, sleet, and external ice formation, making it suitable for outdoor and exposed-location wiring applications. The body is aluminum with a powder-coated silver finish, measuring 4.5 inches in overall height, 2.5 inches in overall width, and 2 inches in overall depth. It includes three 0.75-inch knockouts, and ships complete with a gasket, mounting lugs, plugs, and screws. Licensed electricians and electrical contractors are the primary installers for this type of enclosure.

This outlet box is used in residential and light commercial electrical work where a durable, weather-resistant single-gang box is required. Typical applications include exterior wall outlets, service entry points, and outdoor receptacle installations. The NEMA 3R rating qualifies it for outdoor use in locations exposed to the elements. The included gasket provides a seal against moisture ingress, and the mounting lugs support both horizontal and vertical mounting orientations to accommodate varied field conditions.
