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.

Orbit 4SDB-MC-MS – Frequently Asked Questions

1) Does the Orbit 4SDB-MC-MS 4-inch square box come with MC cable clamps built in, or do I still need connectors?
The clamps are factory-installed in the box. The 4SDB-MC-MS ships with integrated MC clamps that accept metal-clad cable directly, so in many applications you do not need to buy separate MC connectors for those entries. That is the point of the -MC suffix in the part number.
2) How deep is the Orbit 4SDB-MC-MS 4-square box, and why would I pick it over a standard-depth 4S?
It is a 2-1/8 inch deep body on a 4 inch square footprint. The extra depth over a standard-depth 4-square gives you more interior volume for splices, devices, added conductors, and low-voltage components, which is what you want when your box fill calculation is tight. If fill is not an issue, a shallower 4S does the same job in less wall cavity.
3) Will standard mud rings and device rings fit this Orbit 4-square box?
Yes. The 4S footprint is the standard 4-square format, and it accepts the common device rings, mud rings, and covers used on branch-circuit wiring in both commercial and residential work. Rings and covers are not included with the box, so order them separately to match your device count and finished wall depth.
4) Can I mount this box to metal studs, or is the bracket only for wood framing?
Both. The 4SDB-MC-MS arrives with the MS bracket already attached, and that bracket is made for secure mounting to wood or metal studs while holding the box at the right depth relative to the finished wall surface. No separate box hanger or bar is needed for ordinary stud work.
5) Is this the right box for an outdoor or wash-down location?
No. The Orbit 4SDB-MC-MS is a steel 4-square rough-in box for stud-mounted junction, splice, and device work in walls. For a wet, dusty, or wash-down enclosure you want a sealed box instead, such as the Rittal 80181 JB Series hinged-cover junction box rated IP66/NEMA 4X, or a non-metallic screw-cover box like the Carlon E987R.
6) Is a Carlon E987R screw-cover box a substitute for the Orbit 4SDB-MC-MS 4-inch square deep box?
No. The Orbit 4SDB-MC-MS is a 4-inch square welded steel box, 2-1/8 inches deep, with integrated MC clamps and an MS mounting bracket for stud-mounted rough-in, so it accepts standard 4S device rings, mud rings, and covers. The Carlon E987R is a polycarbonate screw-cover junction box measuring 6 by 6 by 4 inches, which is an enclosure-style box for splices behind a screwed-on cover rather than a 4S device box. If the drawing calls for a 4-square opening with a mud ring and MC terminations, the Orbit is the one that fits that prep.
7) I need a junction box for a wet or washdown location instead of an MC rough-in box - what should I use?
The Orbit 4SDB-MC-MS is a welded 4-inch square steel box with MC clamps and an MS bracket, built for dry interior branch-circuit rough-in on studs and framing. For a washdown or exposed outdoor location, look at the Rittal 80181 JB series hinged-cover junction box, which is rated IP66 / NEMA 4X. The Rittal is a sealed standalone enclosure with a hinged cover, so it does not take 4S mud rings or devices the way the Orbit does.
8) Can I use a non-metallic PVC junction box in place of the Orbit 4SDB-MC-MS?
Only if the wiring method changes. The Orbit 4SDB-MC-MS has integrated MC clamps for terminating metal-clad cable directly into a welded steel box, which also carries the equipment ground path through the metal raceway system. The Cantex E983G family is non-metallic PVC, intended for PVC conduit and non-metallic wiring methods, and has no MC clamps. If the job is wired in MC cable, stay with the Orbit steel box; if it is PVC conduit, the Cantex family is the right direction.
9) How many Orbit 4SDB-MC-MS boxes come in a box, and is it sold individually?
It ships as a case of 100 boxes. That is the pack quantity for the 4SDB-MC-MS, which suits contractors roughing in a floor or a whole building rather than buying ones and twos.
10) I need a non-metallic junction box instead of steel. What are my options?
The 4SDB-MC-MS is a metal 4-square with steel MC clamps, so it is not the choice where you want non-metallic. ZenSupply carries PVC and polycarbonate alternatives: the Cantex E983G non-metallic PVC junction box family, the Cantex 5133690 4-1/8 inch junction box with a 1/2 inch knockout and cover, and the Carlon E987R polycarbonate screw-cover box at 6 x 6 x 4 inches. Note that none of those carry integrated MC clamps, so cable terminations get made with separate connectors.
11) Can the Orbit 4SDB-MC-MS be used as a pure junction or splice box with no device in it?
Yes, that is one of its intended uses. It is listed for junction and splice installations as well as device work, and the 2-1/8 inch depth gives you the room to make up splices and still close a flat cover over them. For a blank junction application you would order a flat 4S cover rather than a mud ring.
12) What is the exact manufacturer part number for the Orbit welded 4-square deep box with MC clamps and bracket?
Orbit part number 4SDB-MC-MS. Reading the code: 4SDB is the 4 inch square deep box, MC is the integrated metal-clad clamps, and MS is the included mounting bracket. Depth is 2-1/8 inches and it comes 100 to a case.
13) What is the difference between the Orbit 4SDB-MC-MS and a Cantex 5133690 junction box with knockout and cover?
The Cantex 5133690 is a 4-1/8 inch junction box supplied with a 1/2 inch knockout and a cover, so it arrives as a closed splice box ready to mount. The Orbit 4SDB-MC-MS is a 4-inch square welded box 2-1/8 inches deep that ships with MC clamps already in the box and an MS mounting bracket attached, and no cover or ring is part of the configuration - you select the mud ring or flat cover to match the device and wall thickness. Pick the Cantex when you want a self-contained covered box; pick the Orbit when it is a stud-mounted MC rough-in that will take a device later.
14) For a facility standardizing on one junction box, how do the Orbit 4SDB-MC-MS and the Rittal 80181 split up the work?
They cover different halves of a building. The Orbit 4SDB-MC-MS is the high-volume interior item - a 4-inch square welded deep box, 2-1/8 inches, with MC clamps and an MS bracket, sold 100 to a pack, which is how branch-circuit device and splice boxes get bought for rough-in. The Rittal 80181 is a JB series hinged-cover box rated IP66 / NEMA 4X, which suits mechanical rooms, roof equipment, and washdown areas where a gasketed hinged enclosure is required. Many MRO buyers stock the Orbit by the pack for general rough-in and the sealed enclosure only where the environment demands it.
15) What does welded construction actually get me on a 4-square box?
The seams are fully welded instead of folded or crimped, so the body is a one-piece enclosure that holds its shape through handling, mounting, and cable pulling. Practically, it flexes less when you are torquing a ring on or pulling MC through, and there are fewer gaps at the corners than on a crimped box.
