B-Line Eaton series wireway, 2.5" height, 36" length, 2.5" width, G NK wireway, Thru holes, No knockouts, Screw cover, 1, Steel, Plated screws, ANSI

It's a 2-1/2 by 2-1/2 inch cross section running 36 inches long. That's the smallest of the standard lay-in trough sizes, so it suits control panel gutter runs, small feeder taps and tidying up a group of branch circuits rather than large feeder pulls. If you need more cross sectional area for conductor fill, step up to a 4x4 or 6x6 trough of the same series.

No. The 2236 G NK is a NEMA 1 enclosure, which is indoor, general purpose only, giving protection against incidental contact and falling dirt. It has no gasketing and the cover is held on with plated screws, not a sealed clamp. For a wet or outdoor run you need a NEMA 3R raintight trough instead.

No knockouts. The 2236 G NK is supplied blank, so every conduit entry gets punched where you want it on the job. That's the usual choice when entry locations aren't fixed yet; if you want factory knockouts on the sides and ends, order the knockout version of the trough instead.

Screw cover design. The full length cover lifts off once you back out the plated screws, so the trough becomes a completely open lay-in channel for pulling and dressing conductors, then the cover goes back on. It is not a hinged cover, so plan for clearance in front of the trough to remove the cover and somewhere to set it down.

It is CSA Certified, which is what most specs and inspectors in Canada and many US jurisdictions want to see on a metal wireway. The part number to submit is 2236 G NK, Eaton B-Line series.

Yes, troughs of this series are built to run end to end in 36 inch sections to make up whatever length the wall needs. The connecting hardware and any elbows, tees, end plates or hangers are separate items, so count those into the order along with the number of 36 inch bodies.

16 gauge steel, painted ANSI 61 gray. That's the standard gray used across industrial control gear, so a run of this trough matches the panels, disconnects and enclosures already on most plant and mechanical room walls. The cover screws are plated.
