Thomas Betts DIH4-2-LM Aluminum Outlet Box 1 Gang

Product Description

The THOMAS BETTS DIH4-2-LM is a 1-gang aluminum electrical outlet box designed for weather-resistant installations. Constructed from powder-coated aluminum in a rectangular profile, it measures 4.5 inches overall height, 2.5 inches overall width, and 2 inches overall depth. The box ships with a gasket, mounting lugs, plugs, and screws, making it a ready-to-install solution for electricians working on exposed or outdoor outlet locations. Four 0.75-inch knockouts provide flexible conduit entry options, and the NEMA 3R rating confirms suitability for applications where rain protection is required.

This outlet box is suited for residential and light commercial electrical installations where a surface-mount or exposed conduit system is used. Its horizontal and vertical mount capability gives installers flexibility on wall or structural surfaces. The included gasket supports weatherproof integrity at the box face, making it a practical choice for exterior walls, garages, covered outdoor areas, and service entrances where moisture exposure is a concern.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify absence of voltage before beginning work. Use appropriate conduit connectors sized for 0.75-inch trade-size knockouts, and ensure the included gasket is properly seated when a weatherproof cover is applied. Do not over-tighten mounting screws, as this may distort the box body or compromise the gasket seal.
