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

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.
