B-LINE 101072 GRT NK – Frequently Asked Questions
1) Does this B-Line trough come with knockouts already punched?
No. The NK in 101072 GRT NK means no knockouts, so all four sides and both ends arrive solid. You punch or hole-saw the openings where your conduit actually lands, which is why electricians spec NK for custom runs. If you want factory knockouts to save field time, you need the knockout version of the same trough rather than this one.
2) How is the cover attached, and can one person open it for a pull?
The cover is a screw cover, held on with plated screws all the way around. It's removable rather than hinged, so on a 72 inch length plan to support the cover while you back out the screws, or have a second set of hands. The screw-cover design is what keeps the seal tight, but it does mean more time to open than a hinged or slip-on cover.
3) What gauge steel is this Eaton B-Line trough, and will it hold up in a plant or loading dock area?
Body and cover are 16 gauge steel finished in ANSI 61 gray. Sixteen gauge is the standard weight for commercial and light-industrial wiring trough and takes normal traffic and incidental contact in a mech room, plant aisle, or back-of-house corridor. For areas with vehicle or forklift traffic, put a guard in front of it rather than relying on the sheet metal.
4) Is the B-Line 101072 GRT NK approved for use in Canada?
Yes, the trough is CSA Certified, which is what an inspector in a Canadian jurisdiction will be looking for on a wireway. That makes it usable on Canadian institutional and commercial jobs as well as US work.
5) What is the exact part number I should order for the 10 x 10 x 72 B-Line screw cover trough?
Order it as B-Line 101072 GRT NK, an Eaton B-Line series wiring trough. The digits read as the dimensions, 10 inch height by 10 inch width by 72 inch length, with GRT for the gasketed screw-cover trough and NK for no knockouts.
6) Is the B-Line 101072 GRT NK trough suitable for outdoor or wet locations?
No. The GRT NK designation is a screw-cover gasketed raintight trough without knockouts, but the trough itself is CSA Certified and carries a gasketed screw-cover design; for any wet or damp location install, the cover screws must all be run down and every field-cut opening sealed with a raintight fitting. For a clean indoor-only application in a mechanical or electrical room, an NK (no knockout) trough is fine as-is.
7) Will this trough match the gray on my existing panelboards and disconnects?
Finish is ANSI 61 gray, the same standard gray used across most commercial switchgear, panelboards, and enclosures, so it lines up visually with existing gear on the wall. If your facility is standardized on a custom color, this is a stock ANSI 61 unit and would need field painting.
