No. The 2212 G NK trough is a NEMA 1 enclosure, which is indoor, general-purpose protection only. It keeps fingers and falling dirt out of the wiring, but it is not sealed against rain, washdown, or dust. For an exterior wall, a rooftop run, or a wash-down area you need a NEMA 3R or NEMA 4 raintight trough with a gasketed cover instead.

No knockouts. The 2212 G NK is supplied blind, so every conduit entry gets punched in the field where your run actually lands. That is usually what you want on a short connector piece between two pieces of gear, but plan on a hole punch or step bit on site. If you would rather have factory openings, order a knockout version of the trough instead.

It is a 2-1/2 by 2-1/2 inch cross section, 12 inches long. That small square section is for short jumps between panels, gutters, or control stations where you need a few conductors routed and pulled, not for a large feeder run. Weight is about 2.137 lb, so a single installer handles it one-handed.

It is a screw cover, held to the body with plated screws, so the cover lifts completely off for pulling conductors and goes back on with the same fasteners. Removable rather than hinged, which means you need clearance in front of the trough and a screwdriver each time you open it. On a run you expect to re-enter often, a hinged-cover gutter is easier to live with.

Mounting is through holes in the body, so it bolts or screws flat to a wall, backboard, or strut. The anchors, bolts, or strut hardware are yours to supply, chosen for the substrate you are fastening to. Nothing about the trough dictates the fastener size.

The body is 16 gauge steel finished in ANSI 61 gray, the standard gray used on switchgear and panelboards, so it matches most existing electrical equipment without repainting. It is also CSA Certified.

Eaton B-Line part number 2212 G NK. The 22 is the 2-1/2 by 2-1/2 inch section, the 12 is the length in inches, and NK means no knockouts. Specify that full string when you order so you do not receive the knockout version.

Yes, that is the typical use for a 12 inch length. With a 2-1/2 inch square section and through-hole mounting it works as a short connector or nipple between two enclosures or as an extension on a same-size run, with conduit or connector holes punched in the field since it ships without knockouts. Keep it indoors only, as it is a NEMA 1 body.
