B-Line Eaton series wireway, 10" height, 48" length, 10" width, G NK wireway, Thru holes, No knockouts, Screw cover, 1, Steel, Plated screws, ANSI 61

It's a 10 inch by 10 inch cross section running 48 inches long. That 100 square inch opening is the largest of the common square-trough sizes, so it's what you use for a main gutter feeding a panel lineup or a splice trough carrying multiple large feeders, rather than a 4x4 or 6x6 branch run.

No. The NK designation means no knockouts, so the sides, bottom and ends come solid. You drill or punch your own conduit entries wherever the run needs them. If you want factory knockouts on standard centers, order the knockout version instead of the NK.

No. The 101048 G NK is a NEMA 1 screw cover trough, which is general purpose indoor only. It's dust and drip resistant at best, not weatherproof. For outdoors, a rooftop run, or a washdown area you need a NEMA 3R or 4 raintight wireway with a gasketed cover.

It mounts through holes in the back of the trough, so you fasten it directly to a wall, backboard or strut with your own hardware. Anchors, bolts and strut are not part of the wireway. At 33.577 lb per 48 inch section before any conductors go in, back the mounting into structure or strut rather than drywall alone, and support each section.

Each 48 inch section is a straight length of trough with its screw cover. A run also needs connectors between sections, end plates to close the run out, and any elbows or tees where it turns, plus your own mounting hardware since it fastens through holes in the back. Conduit entries you make yourself, because the NK version ships with no knockouts.

It's a screw cover, held on with plated screws along the flange. You back the screws out to lay the cover off and gain full open access down the length of the trough for pulling and splicing. That's slower to open than a hinged cover, so if you expect to be in and out of the trough often, a hinged version is the better choice.

14 gauge steel, painted ANSI 61 gray. That's the standard heavy commercial and industrial gutter thickness, stiff enough to span between supports on a 48 inch section without oil canning and to take screw cover fastening repeatedly. It's a painted finish, so keep it to dry indoor areas; corrosive or wet spaces call for stainless or a coated enclosure.

It's CSA Certified, which covers installations in Canada and is commonly accepted alongside US listings by inspectors. Order it by the B-Line part number 101048 G NK so the submittal matches what lands on site.

ANSI 61 gray is the standard light gray used across most switchgear, panelboards and control enclosures, so a run of this trough above or between existing gear will read as the same color family. Paint batches and age will show some variation against equipment that has been in service a while.
