Orbit 5SDB-MKO 4-11/16" Square Welded Outlet Box, 2-1/8" Deep with MKO

The Orbit 5SDB-MKO is a 4-11/16" square (5S) welded outlet box built with a 2-1/8" deep body to provide extra interior volume for junction, splice, and device applications where a standard-depth square box won't accommodate the wiring or fixture requirements. This box is supplied with an MKO (mounting/knockout) configuration, giving installers a ready-made solution for mounting fixtures, devices, or covers directly to the box without additional field modification. The welded construction of the 5S box provides a solid, one-piece body designed for durability in commercial and industrial electrical rough-in work. As a 4-11/16" square footprint box, the 5SDB-MKO is compatible with the wide range of covers, mud rings, and device plates sized for the 5S square box family, making it a versatile choice for new construction and retrofit electrical projects that call for a larger-capacity outlet box.

Key Features

  • Trade Size: 4-11/16" square (5S) footprint for compatibility with standard 5-square device rings, covers, and plates.
  • Extra Depth: 2-1/8" deep body provides additional interior wiring space compared to standard-depth square boxes.
  • Welded Construction: One-piece welded body for a solid, durable enclosure suited to demanding rough-in installations.
  • MKO Configuration: Supplied with MKO mounting/knockout provisions to simplify device, fixture, or cover installation.
  • Square Box Format: 4-11/16" square design accepts industry-standard mud rings and covers for a range of device and junction applications.

Orbit 5SDB-MKO – Frequently Asked Questions

1) Will standard 4-11/16 inch mud rings and covers fit the Orbit 5SDB-MKO box?
Yes. The 5SDB-MKO uses the 4-11/16 inch square (5S) footprint, so it accepts the device rings, mud rings, covers and plates made for the 5S square family. The extra depth is in the body, not the opening, so cover selection is unaffected.
2) How deep is the Orbit 5SDB-MKO square box, and why would I pick it over a standard-depth 5S box?
The body is 2-1/8 inches deep, which is deeper than a standard-depth square box. Electricians reach for it when the box has to hold more conductors, splices or a fixture's wiring and a shallower 5S box runs out of room, without changing to a different box footprint.
3) We need an outdoor box for a 3-gang device on an exterior wall. Is the Orbit 5SDB-MKO the right choice?
For an exposed exterior 3-gang device, the Mulberry 30601 Royal Mountie is the closer fit: it is a powdered die cast aluminum 3-gang weatherproof outlet box. The Orbit 5SDB-MKO is a welded 4-11/16 inch square (5S) steel box, 2-1/8 inch deep with MKO provisions, intended for commercial and industrial rough-in, junction, and splice work where standard 5S covers and mud rings are used. Choose the Orbit box when the opening is a 5S square rough-in and the Mulberry when the spec calls for a weatherproof 3-gang enclosure.
4) Can the Thomas & Betts 2IH3-1 Red-Dot box be used in place of the Orbit 5SDB-MKO?
They serve different rough-in situations. The Orbit 5SDB-MKO is a 4-11/16 inch square (5S) welded outlet box with a 2-1/8 inch deep body and MKO provisions, sized to take standard 5S mud rings, covers, and device plates for junction, splice, and device work. The Thomas & Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 inch hubs, so it is built around threaded hub conduit entries and a 2-gang device opening rather than the 5S square footprint and cover family. If the drawing calls for a 5S square box with a mud ring, the Orbit box is the match; if it calls for a hubbed conduit body with 1/2 inch entries, the Red-Dot is. Both are supplied in packs of 100.
5) What does MKO mean on the Orbit 5SDB-MKO outlet box?
MKO is the mounting/knockout configuration the box ships with. It gives you the provisions to mount devices, fixtures or covers straight to the box without field-modifying it. The box is also listed as welded construction, so the body is one piece rather than crimped.
6) Is the Orbit 5SDB-MKO sold individually or by the case?
It comes as a pack of 100 boxes, which is how a rough-in crew normally buys them. Order quantity 1 gets you the full 100-count carton, not a single box. The manufacturer part number is 5SDB-MKO.
7) Does the Orbit 5SDB-MKO come with a cover or mud ring?
No cover or ring is included. The 5SDB-MKO is the box body only, in the MKO welded configuration, so you order the 5S mud ring, blank cover or device plate separately to match the device and the finished wall depth.
8) What is a simpler box than the Orbit 5SDB-MKO for residential multi-gang work?
The Cantex EZ Box series is a PVC multi-gang residential outlet box, which is the lighter-duty, nonmetallic route for house wiring. The Orbit 5SDB-MKO is a welded steel 4-11/16 inch square (5S) box, 2-1/8 inch deep with MKO provisions, built for commercial and industrial rough-in and for junction or splice runs that need the extra interior volume a standard-depth square box does not give. If the job is a residential multi-gang device box in PVC, the Cantex EZ fits; if it is a 5S square metal rough-in taking standard mud rings, the Orbit does.
