Orbit D4SB Series 1-1/2" Deep 4" Square Junction Box, Drawn Steel, Pack of 100

Orbit D4SB Series 1-1/2" Deep 4" Square Junction Box

The Orbit D4SB Series is a family of drawn-steel 4" square (4S) junction boxes built for junction, outlet, and device box applications in residential, commercial, and industrial wiring systems. Every box in the D4SB Series shares a 1-1/2" deep drawn-steel body and the standard 4S footprint, with the series available in multiple knockout (KO) configurations to match jobsite requirements: the D4SB-50 features a 1/2" KO, the D4SB-75 features a 3/4" KO, and the D4SB-50/75 provides a combination 1/2"-3/4" KO for added flexibility on conduit or cable entry. Across every model, the drawn construction process produces a seamless, one-piece box body that resists deformation and provides consistent wall thickness for dependable field performance on the jobsite. This makes the D4SB Series a practical, code-familiar choice for splicing conductors, mounting devices, and protecting wiring connections behind walls, ceilings, and other concealed locations.
