Orbit 4SB-MC-WB 4" Square Welded Box with MC Clamps & WB Bracket, 1-1/2" Deep

The Orbit 4SB-MC-WB is a 4" square (4S) welded outlet box built to a 1-1/2" deep profile, engineered for electricians who need a rugged, code-ready junction and device enclosure. This box ships with integrated MC clamps for fast, secure termination of metal-clad cable directly into the enclosure, eliminating the need for separate connectors and speeding up rough-in on commercial and residential jobs. A WB (wall bracket) mounting bracket is factory-installed, giving installers a reliable, pre-positioned mounting reference for accurate placement in stud-frame and wall-cavity applications. The welded seam construction of this 4-square box provides a solid, one-piece body that resists flexing and racking during cable pulls, device installation, and cover-plate attachment, making it a dependable choice wherever a durable steel junction box is specified.

Key Features

  • 4" Square Footprint: Standard 4S box sizing accepts common device rings, covers, and mud rings used throughout commercial and residential wiring.
  • 1-1/2" Deep Body: Provides ample interior volume for splices, device wiring, and cable slack while meeting standard box-fill requirements for typical branch-circuit work.
  • Welded Construction: A one-piece welded body delivers a rigid, durable enclosure that stands up to jobsite handling, cable tension, and repeated device servicing.
  • Integrated MC Clamps: Built-in clamps are designed specifically for metal-clad (MC) cable, allowing quick, secure cable termination without add-on connectors.
  • WB Mounting Bracket: The factory-installed wall bracket simplifies positioning and fastening the box to framing members, saving install time on new construction and remodel work.
  • Steel Body: Constructed from steel for the strength and grounding continuity electrical contractors expect from a standard 4-square junction box.

Technical Specifications

  • Box Size: 4" Square (4S)
  • Depth: 1-1/2"
  • Construction: Welded steel body
  • Cable Clamps: Integrated MC (metal-clad cable) clamps
  • Mounting: WB wall bracket, factory-installed

Typical Applications

  • Commercial and Residential Rough-In Wiring
  • Metal-Clad (MC) Cable Installations
  • New Construction Wall-Cavity Mounting
  • Device, Switch, and Receptacle Housing
  • Junction and Splice Enclosures

Orbit 4SB-MC-WB – Frequently Asked Questions

1) Does the Orbit 4SB-MC-WB 4-inch square box need separate MC cable connectors?
No. The 4SB-MC-WB has MC clamps built into the box, so metal-clad cable terminates directly in the enclosure without add-on connectors. That is the main labor saving on an MC rough-in: strip, clamp, done. If you are pulling EMT instead, you would want a plain 4S box with knockouts and your own fittings, since these clamps are made for MC cable.
2) What does the WB bracket on this Orbit 4-square box mount to?
The WB wall bracket is factory installed and is meant for fastening the box to framing members in stud-frame and wall-cavity work, giving you a fixed mounting reference for depth and position. It suits new construction and remodel rough-in. If you are mounting to a surface or a masonry wall rather than framing, a bracketless 4S box is the easier choice.
3) How deep is the Orbit 4SB-MC-WB box, and will it take a device ring?
The body is 1-1/2 inches deep in a standard 4 inch square (4S) footprint, so it accepts the common device rings, mud rings and covers used on commercial and residential wiring. The 1-1/2 inch depth gives you room for splices, device wiring and cable slack on typical branch-circuit work.
4) What should I use instead of the Orbit 4SB-MC-WB for an outdoor or wet location box?
The Orbit 4SB-MC-WB is a welded steel 4 inch square box with integrated MC clamps and a factory-installed WB wall bracket, intended for interior rough-in in stud framing and wall cavities. For an exterior surface location, look at the Mulberry 30601 Royal Mountie, a powdered die cast aluminum 3-gang weatherproof outlet box, or the Thomas and Betts 2IH3-1 Red-Dot 2-gang conduit outlet box with three 1/2 inch hubs. Those two are hub-and-gasket style boxes fed by conduit rather than clamped MC cable, so the wiring method changes along with the box.
5) Is a PVC box like the Cantex EZ Box an alternative to the Orbit 4SB-MC-WB?
They serve different wiring methods. The Cantex EZ Series is a PVC multi-gang residential outlet box, non-metallic, so it does not provide a metal raceway for grounding continuity and is not built to clamp metal-clad cable. The Orbit 4SB-MC-WB is a steel 4 inch square welded box with integrated MC clamps, so on a job specified for MC cable the steel box with clamps is the matching part; the PVC box suits nonmetallic-sheathed residential work.
6) Is the Orbit 4SB-MC-WB sold individually or by the case?
It ships 100 boxes to the pack, which is how contractors buy them for a full rough-in rather than a one-off repair. Part number is 4SB-MC-WB.
7) What is the non-metallic alternative if I am running NM cable in a house instead of MC?
A steel box with MC clamps is the wrong tool for a residential NM job. Look at the Cantex EZ Series PVC multi-gang residential outlet box instead. Keep the Orbit 4SB-MC-WB where the spec calls for steel and metal-clad cable, since the steel body also carries the grounding continuity electricians expect from a 4-square.
8) Which of these boxes is multi-gang out of the box?
The Mulberry 30601 Royal Mountie is a 3-gang weatherproof box and the Thomas and Betts 2IH3-1 Red-Dot is a 2-gang box, so both carry their gang count in the body. The Orbit 4SB-MC-WB is a 4 inch square box, which takes standard device rings and mud rings to set the gang configuration at trim-out rather than fixing it at rough-in.
9) Is a welded 4-square box better than a drawn or sectional one for MC pulls?
Welded means a one-piece body with a welded seam, which resists flexing and racking while you pull cable, land devices and screw down cover plates. On jobs where boxes get handled hard or cables get tensioned, that rigidity is the reason the welded version gets specified over lighter constructions.
10) Will the Orbit 4SB-MC-WB work as a junction or splice box, not just a device box?
Yes, it serves both. The 1-1/2 inch deep 4S body is used for housing switches and receptacles behind a ring, and equally as a junction or splice enclosure on branch circuits, with the MC clamps terminating cable at each entry.
