B-Line Eaton series wireway, 12" height, 60" length, 12" width, G NK wireway, Thru holes, No knockouts, Screw cover, 1, Steel, Plated screws, ANSI 61

No. The 121260 G NK is a NEMA 1 wireway, which is general purpose indoor only, for protection against falling dirt and incidental contact. For a rooftop, exterior wall, or washdown area you need a NEMA 3R or NEMA 4 raintight or watertight wireway instead.

No knockouts. The 121260 G NK body is blank, so every conduit entry gets field drilled or punched where you want it. If you would rather have factory openings on the sides, you need a knockout (KO) version rather than the NK designation.

The 121260 G NK ships as a trough and screw cover with plated screws only. To build out a run you add couplings between sections, end plates or closing plates at the terminations, and any elbows or tees for direction changes, sized to the 12 x 12 cross section. Conduit fittings are separate too, since there are no knockouts to start from.

14 gauge steel, painted ANSI 61 gray. That gauge keeps a 12 x 12 trough rigid over a 60 inch span without oil canning, and ANSI 61 gray is the standard industrial control gray, so it matches panelboards, enclosures, and existing gutter runs in most plants.

Yes, it is CSA Certified, which covers installations under the Canadian Electrical Code as well as work specified to CSA on this side of the border.

If the existing run is 12 x 12 NEMA 1 screw cover gutter in ANSI 61 gray, the 121260 G NK lines up on cross section, enclosure type, and color, so it extends the run and looks the same. Confirm the existing sections are also screw cover rather than hinged, since the two covers are not interchangeable, and check whether the old body had factory knockouts you were relying on.

Order it as B-Line 121260 G NK. The number reads as the dimensions and type: 12 inch height, 12 inch width, 60 inch length, G NK wireway with no knockouts.
