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

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

The Orbit 4SDB-MC-MS is a 4" square (4S) deep electrical box, welded construction, measuring 2-1/8" in depth. This box is factory-equipped with integrated MC clamps for fast, code-compliant termination of metal-clad cable directly into the box, and it ships with an MS mounting bracket for secure attachment to studs or framing during rough-in. The welded seams provide a rigid, one-piece enclosure body that resists flexing during installation and long-term service, making this box a dependable choice for junction, splice, and device applications on commercial and residential electrical projects.

Key Features

• Trade Size: 4" square footprint with a 2-1/8" deep body, giving installers extra interior volume for splices, devices, and additional conductor fill compared to shallower 4S boxes.
• Welded Construction: Fully welded seams create a solid, one-piece box that holds its shape during handling, mounting, and cable pulling, reducing gaps versus folded or crimped box designs.
• Integrated MC Clamps: Built-in clamps are designed to accept metal-clad (MC) cable directly, eliminating the need for separate connectors in many applications and speeding up rough-in labor.
• MS Mounting Bracket Included: The box arrives with an MS bracket attached, simplifying secure mounting to wood or metal studs and helping installers maintain proper box depth relative to the finished wall surface.
• 4-Square Format: The 4S sizing is a standard, widely compatible footprint that accepts common device rings, mud rings, and covers used throughout commercial and residential branch-circuit wiring.
• Deep Box Design: The extra 2-1/8" depth over standard-depth 4-square boxes provides additional room for conductors, devices, and low-voltage components where box fill calculations require more interior space.
