Orbit T5B-50200 5" Square Junction Box with MKO/CKO Knockouts

The Orbit T5B-50200 5" Square Junction Box with MKO/CKO Knockouts is a versatile electrical enclosure designed for splicing, pulling, and routing conductors in a variety of residential and commercial wiring applications. This 5" square configuration is engineered with multiple knockout options built directly into the housing, giving installers flexibility to accommodate different conduit sizes on the same job without needing a separate box for every conduit size. The box features 1/2" to 1" MKO (multi-knockout) openings along with 1" to 2" CKO (concentric knockout) openings, allowing electricians to select the exact conduit entry size required for each run while keeping unused knockouts sealed until needed. This dual-knockout design reduces the number of box SKUs a contractor needs to stock and speeds up rough-in work by eliminating guesswork on conduit sizing in the field.

Key Features

  • Box Size: 5" square configuration provides ample interior working space for splices, taps, and conductor routing.
  • MKO Knockouts: 1/2" to 1" multi-knockout openings let installers select the exact conduit entry size needed on site.
  • CKO Knockouts: 1" to 2" concentric knockout openings extend conduit-size flexibility for larger conduit runs entering the same box.
  • Dual Knockout Design: combining MKO and CKO knockout styles in one enclosure minimizes the number of box variants needed to stock for mixed conduit-size jobs.
  • Square Box Format: the 5" square footprint is a common form factor for junction, pull, and splice applications where multiple conduit entries converge.

Technical Specifications

  • Box Configuration: 5" Square
  • Multi-Knockout (MKO) Range: 1/2" to 1"
  • Concentric Knockout (CKO) Range: 1" to 2"

Typical Applications

  • Conduit and Raceway Junction Points
  • Splicing and Pull-Box Installations
  • Commercial and Industrial Electrical Rough-In
  • Mixed Conduit-Size Wiring Runs
  • New Construction and Renovation Electrical Work

Orbit T5B-50/200 – Frequently Asked Questions

1) What junction box should I use instead of the Orbit T5B-50200 for a wet or washdown location that needs a NEMA 4X enclosure?
Use the Rittal 80181 JB Series hinged-cover junction box, which is rated IP66/NEMA 4X. The Orbit T5B-50200 is a 5 inch square junction box with 1/2 inch to 1 inch MKO and 1 inch to 2 inch CKO knockouts, intended for splicing, pulling, and routing conductors in residential and commercial wiring; the Rittal box is the one in the group carrying a sealed-enclosure rating with a hinged cover for repeated access.
2) For a 2 inch conduit entering a pull box, which of these boxes handles it?
The Orbit T5B-50200 is the one with stated capacity for that size: its concentric knockout openings run 1 inch to 2 inch, alongside 1/2 inch to 1 inch multi-knockout openings, in a 5 inch square housing used for junction, pull, and splice points. The Cantex 5133690, by comparison, is a 4-1/8 inch box furnished with a 1/2 inch knockout and cover, which is a small-conduit box.
3) What is the difference between MKO and CKO knockouts on a square junction box?
An MKO, or multi-knockout, is a stepped opening you punch out to the size you want within its range, 1/2 inch to 1 inch on the Orbit T5B-50200. A CKO, or concentric knockout, is a set of nested rings you remove one at a time to step up the opening, 1 inch to 2 inch on this box. Both let you pick the conduit size in the field; the CKO is there for the larger feeder entries.
4) Can I use a 5 inch square box as a pull box for conduit runs?
Yes. The 5 inch square format on the Orbit T5B-50200 is sized for junction, pull, and splice work where several conduits converge, and the interior gives room for splices, taps, and conductor routing. Orbit lists conduit and raceway junction points, pull-box installations, and commercial and industrial rough-in as its intended uses.
5) What is the correct part number to order for the Orbit 5 inch square junction box?
Order it as Orbit T5B-50200, printed by the manufacturer as T5B-50/200. It is a single configuration, the 5 inch square box, so there are no size or finish choices to specify.
6) Does the Orbit T5B-50200 junction box come with a cover?
The T5B-50200 is supplied as the 5 inch square box with its MKO and CKO knockouts; a cover is specified separately. If you want a box and cover together, the Cantex 5133690 4-1/8 inch junction box is listed with a 1/2 inch knockout and cover.
7) Should I use a metal knockout box or a non-metallic PVC junction box for my conduit run?
Match the box to the raceway system. A knockout box like the Orbit T5B-50200, with 1/2 inch to 1 inch MKO and 1 inch to 2 inch CKO entries, is built for conduit and raceway junctions where you punch the entry to size in the field. If you are running PVC conduit and want a non-metallic enclosure throughout, the Cantex E983G non-metallic PVC junction box family is the alternative we carry.
8) Is there a non-metallic alternative to the Orbit T5B-50200 square junction box?
Yes. The Cantex E983G is a non-metallic PVC junction box family, and the Carlon E987R is a polycarbonate screw-cover junction box measuring 6 inch by 6 inch by 4 inch. The Orbit T5B-50200 is a 5 inch square junction box whose knockout pattern covers 1/2 inch to 1 inch MKO and 1 inch to 2 inch CKO entries, so if your runs need that mixed conduit-size entry in one box, confirm the non-metallic option you pick accepts the same conduit sizes.
9) Will one box type cover a job with several different conduit sizes?
That is the point of the Orbit T5B-50200. Because it carries both 1/2 inch to 1 inch MKO openings and 1 inch to 2 inch CKO openings in the same housing, a contractor can stock one 5 inch square box instead of separate boxes per conduit size, and decide the entry size at rough-in.
