Orbit 4SDB-MC-B 4" Square Deep Box, Welded, MC Clamps & B Bracket, Pack of 100

Orbit 4SDB-MC-B 4" Square Deep Box, Welded, MC Clamps & B Bracket

The Orbit 4SDB-MC-B is a 4" square (4S), 2-1/8" deep electrical outlet box built as a welded assembly for added rigidity on jobsite installations. This deep box configuration comes equipped with factory-installed MC clamps for quick, secure termination of MC cable directly into the box, eliminating the need for separate connectors in many applications. A B bracket is included, giving installers a pre-mounted fastening point for attaching the box to framing members, studs, or other structural supports without additional hardware sourcing. The 2-1/8" depth provides extra interior volume compared to standard 1-1/2" deep boxes, which is useful when device fill, multiple conductors, or larger devices require more working space inside the enclosure. As a welded 4-square box, the Orbit 4SDB-MC-B is intended for use as a standard junction, outlet, or device box in residential, commercial, and light industrial branch-circuit wiring where MC cable is the raceway method of choice. Electricians and contractors rely on boxes like this for dependable rough-in work that meets the everyday demands of new construction and remodel projects alike.

Key Features

• Size: 4" square (4S) footprint sized to accept standard square-box covers, mud rings, and devices common to 4-square installations.
• Deep Box Depth: 2-1/8" deep design provides additional interior capacity over shallow boxes, supporting easier conductor management and device fill.
• Welded Construction: Fully welded seams deliver a rigid, one-piece box body that resists flexing during installation and cable pulling.
• Integrated MC Clamps: Built-in MC clamps allow direct termination of MC cable into the box, streamlining rough-in and reducing the need for add-on connectors.
• B Bracket Included: A pre-attached B-style mounting bracket simplifies fastening the box to framing, studs, or other structural members.
• Jobsite-Ready Assembly: Clamps and bracket arrive factory-installed, cutting down on assembly time and small-parts handling in the field.
