Orbit 4SDB-MKO-PT 4" Square Deep Box, Galvanized Steel

Orbit 4SDB-MKO-PT 4" Square Deep Box, Galvanized Steel

The Orbit 4SDB-MKO-PT is a 4-Inch x 4-Inch x 2-1/8-Inch deep square (4S) outlet box built from galvanized sheet steel for long-term corrosion resistance in commercial and industrial electrical rough-in work. Constructed with a welded seam for a rigid, uniform enclosure, this deep box offers 30.3 cubic inches of usable volume, giving installers extra room for device connections, wire splices, and conductor fill on circuits that require additional box capacity. It is equipped with MKO (multiple knockout) openings and PT (pryout) configurations, providing flexible conduit entry points for a variety of raceway sizes without requiring field-drilled holes. As a standard 4-Inch square deep box, it accepts common device rings, covers, and mud rings to adapt the enclosure for switches, receptacles, or junction applications. The welded construction and galvanized steel finish make this box a dependable choice for new construction, renovation, and commercial panel and device wiring where a deep-capacity 4S box is specified.
