Orbit Industries 4SDB-75-FB Flush Mount Galvanized Switch Box

Product Description

The ORBIT INDUSTRIES 4SDB-75-FB is a flush-mount galvanized steel switch box designed for residential and commercial electrical wiring installations. Formed from 16-gauge sheet steel with a galvanized finish, this 4-inch by 4-inch by 2-1/8-inch box provides a sturdy, corrosion-resistant enclosure for switches, receptacles, and wiring devices. Six 3/4-inch knockouts on the sides and four 3/4-inch plus one 1/2-inch knockout on the bottom give installers flexible conduit entry options. The included bracket supports flush mounting in standard wall and ceiling assemblies.

This switch box is suited for new construction and retrofit wiring work in both residential and light commercial settings. Its 4-inch by 4-inch footprint and 2-1/8-inch depth accommodate standard wiring devices and allow adequate wire fill. Electricians typically use this box in conduit-fed branch circuit installations where a flush, clean finish at the wall surface is required. The galvanized finish provides corrosion resistance appropriate for dry and damp interior locations.
