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.

Orbit 4SDB-MC-B – Frequently Asked Questions

1) Does the Orbit 4SDB-MC-B 4 inch square box come with MC cable clamps already installed, or do I need separate connectors?
MC clamps come factory-installed inside the Orbit 4SDB-MC-B, so MC cable terminates directly into the box without add-on connectors in most applications. That is the whole point of the -MC suffix: the clamps and the bracket ship attached, so there are no loose small parts to handle at rough-in.
2) How deep is the Orbit 4SDB-MC-B 4 inch square box, and will it give me enough volume for two devices and multiple conductors?
It is a 2-1/8 inch deep 4-square box, the deep version rather than the 1-1/2 inch shallow one. That extra depth is what you want when you are stacking conductors, splicing a circuit through the box, or mounting a larger device behind a two-gang mud ring. If your fill calculation is tight on a shallow 4S, this is the box that solves it.
3) What does the B bracket on this Orbit 4 inch square box mount to?
The pre-attached B-style bracket gives you a fastening point for screwing or nailing the box straight to a stud, framing member, or other structural support. No separate box hanger or bar hanger needed for standard stud-mounted outlet work. If your application is conduit-supported or needs a different offset, you would want a plain box without the bracket instead.
4) I am wiring romex in a residential remodel, not MC. Is this the right box?
Not the best fit. The clamps in the 4SDB-MC-B are MC clamps, so they are sized to grip MC cable armor, and the box is the one to use when MC is your wiring method. For nonmetallic residential work, a PVC device box like the Cantex EZ Box multi-gang residential outlet box is the usual choice, or a steel 4S box ordered with NM clamps instead.
5) Can I use the Orbit 4SDB-MC-B outside on a wet-location receptacle, or do I need a different box?
The 4SDB-MC-B is a welded 4 inch square deep box with MC clamps and a B bracket, built for branch-circuit rough-in in residential, commercial, and light industrial work, typically fastened to framing inside a wall. For an exposed outdoor receptacle, a weatherproof box is the usual choice: the Mulberry 30601 Royal Mountie is a powder-coated die cast aluminum 3-gang weatherproof outlet box. Bear in mind the Mulberry is a 3-gang box, so your device count and cover need to match it, not the 4 inch square pattern.
6) The Orbit 4SDB-MC-B has MC clamps, but my run is in 1/2 inch conduit on an exposed exterior wall. What box should I use instead?
Use a hub-style conduit box rather than an MC-clamp box. The Orbit 4SDB-MC-B is a 4 inch square deep outlet box with integrated MC clamps for terminating MC cable directly into the box, so it is matched to MC cable rough-in rather than threaded conduit. For a conduit connection, the Thomas & Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 inch hubs, so the raceway threads straight into the body. Note the gang count differs: the Orbit is a 4 inch square box that takes square covers and mud rings, while the 2IH3-1 is a 2-gang conduit body.
7) Will standard 4-square covers and mud rings fit the Orbit 4SDB-MC-B?
Yes. The footprint is a standard 4 inch square (4S), so it takes the usual square-box flat covers, raised covers, and mud rings, plus devices common to 4-square installs. You order the ring separately based on your wall finish depth and gang count.
8) Is the Orbit 4SDB-MC-B sold individually or by the case?
It ships 100 boxes to the pack. That is a rough-in quantity, sized for a floor or a whole house rather than a single replacement, so plan the order around a full job.
9) Can the Orbit 4SDB-MC-B be used as a junction box, not just a device box?
Yes, it works as a junction, outlet, or device box on branch circuits. The 2-1/8 inch depth is the reason it works well for splices: you get room to dress conductors and land wirenuts behind a flat cover instead of fighting fill in a shallow box.
10) What is the manufacturer part number to order the Orbit 4 inch square deep MC box with the B bracket?
Order Orbit part number 4SDB-MC-B. The designation reads out as 4S deep box, MC clamps, B bracket, so a box without the bracket or with a different clamp type carries a different number.
11) We wire houses with nonmetallic cable, not MC. Is the Orbit 4SDB-MC-B the wrong box for us?
It is matched to a different wiring method. The 4SDB-MC-B is a metal 4 inch square deep box whose integrated MC clamps terminate MC cable directly, which is the reason to pick it. For residential nonmetallic work, the Cantex EZ Box is a PVC multi-gang residential outlet box, a nonmetallic enclosure rather than a welded steel 4-square. The two also differ in form: the Orbit takes standard 4 inch square covers, mud rings, and devices, while the Cantex is a multi-gang residential box.
12) I need a hundred boxes for a commercial MC rough-in. Does the Red-Dot 2IH3-1 work as a substitute for the Orbit 4SDB-MC-B at that quantity?
Both are sold in 100-piece packs, but they are not interchangeable. The Orbit 4SDB-MC-B is a welded 4 inch square, 2-1/8 inch deep box with factory MC clamps and a B bracket for fastening to studs and framing. The Thomas & Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 inch hubs, so MC cable would need separate connectors and the box has no stud bracket in its description. If the raceway method is MC cable into a framed wall, stay with the 4SDB-MC-B.
13) What is the difference between a welded 4-square box and a drawn or crimped one?
The Orbit 4SDB-MC-B body is fully welded, so the seams are joined into a rigid one-piece shell that does not flex when you are pulling cable or torquing the bracket screws. For MC rough-in where you are tugging cable through clamps on a mounted box, that rigidity is the practical difference.
