Thomas Betts DIH5-1-LM Aluminum Outlet Box 1 Gang

Product Description

The THOMAS BETTS DIH5-1-LM is a single-gang aluminum outlet box designed for electrical wiring installations requiring a weather-resistant enclosure. Constructed from powder-coated aluminum in a rectangular profile, this box measures 4.5 inches in overall height, 2.5 inches in overall width, and 2 inches in overall depth. It is rated NEMA 3R, meaning it is built to withstand falling rain and ice formation without compromising the integrity of enclosed devices. Licensed electricians install this box in exposed or semi-exposed locations where a standard plastic box is not appropriate for the environment or code requirement.

This outlet box is suited for residential and light commercial electrical applications where weatherproof or weather-resistant wiring device enclosures are required. It supports horizontal and vertical mounting configurations, giving installers flexibility in how the box is oriented on the structure. The box ships with a gasket, mounting lugs, plugs, and screws included, reducing the need for separate hardware sourcing on the job. Five 1/2-inch knockouts allow for conduit entry from multiple directions to accommodate the run layout.

Compatibility

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit at the panel and verify zero voltage with a meter before beginning work. Seal conduit entries properly to maintain the NEMA 3R rating after installation. Do not exceed the box fill capacity as calculated per NEC Article 314.
