B-Line Eaton series wireway, 12" height, 48" length, 12" width, HSNK wireway, Thru holes, No knockouts, Hinged cover, 1, Steel, Hinged, ANSI 61 gray,

It's a 12 inch by 12 inch cross section, 48 inches long. That's one of the larger lay-in trough sizes, so it suits feeder pulls and panel gutter runs where a 4 x 4 or 6 x 6 wireway would exceed fill. Body and cover are 14 gauge steel, and it weighs 41.244 lb, so plan two people or a lift for overhead mounting.

No. The 121248 HSNK is a NEMA 1 enclosure, which is indoor use only, general purpose protection against incidental contact and falling dirt. It is not raintight or gasketed. For an outdoor run or a washdown area you need a NEMA 3R or 4 wireway instead.

No knockouts. The 121248 HSNK ships with a blank body, so every conduit entry gets field punched where you want it. Mounting is by thru holes in the back of the trough. If you would rather not punch in the field, order a knockout version of the wireway instead.

This one is hinged, and the hinge is the reason to pick it. On a 48 inch section at 12 x 12, a loose screw cover is heavy and awkward to hold overhead while you dress conductors; the hinged cover swings open and stays with the trough. The cover still secures to the body with plated screws once closed, so it is not a latch-only lid. Choose a screw cover version only where you need the lid fully removable or where side clearance won't let a cover swing.

It is certified to CSA C22.2, so it can be specified on Canadian Electrical Code work as well as US installations.

Yes. The 121248 HSNK is a single 48 inch straight section. To extend a run you order additional sections plus the 12 x 12 connectors, and any elbows, tees or end plates the layout calls for are separate items as well. Because the body ships with no knockouts, field punching for conduit entries is part of the install.

The finish is ANSI 61 gray, the standard light gray used on most commercial switchgear, panelboards and wireway. It will read as a match alongside other ANSI 61 equipment in the same room.

14 gauge is the standard wall thickness for large lay-in wireway of this size, and it is what both the body and hinged cover use here. Support it through the thru holes in the back at the intervals your layout and code require, rather than relying on the trough to span long unsupported distances. The section weighs 41.244 lb empty, before conductors.
