B-Line Eaton series wiring trough, 6" height, 12" length, 6" width, GTGV NK wiring trough, Thru holes, No knockouts, Screw cover, 1, Galvanized steel

The 6612 GTGV NK is a 6 x 6 inch trough body 12 inches long: 6 inch height, 6 inch width, 12 inch length. That 6 x 6 cross-section is the number that matters for conductor fill and for lining up with other 6 x 6 gutter sections and fittings on the same run.

No. The NK in 6612 GTGV NK means no knockouts, so the galvanized body ships blank. You drill or punch your own conduit entries wherever the run needs them, which is what most installers want on a gutter feeding multiple directions. If you would rather not punch holes in the field, order a knockout version instead.

No. It is a NEMA 1 enclosure, which is indoor, dry-location only, giving protection against incidental contact and falling dirt. It is not rain, dust, or hose-down rated. For an exterior wall, a wet mechanical room, or a car wash, you need a raintight NEMA 3R gutter instead.

Screw cover. The lid is held on by plated screws, so you back the screws out to open it and reinstall them to close. That gives a tamper-resistant closure for an electrical room or a tenant space, but it means the cover is not hinged, so leave screwdriver clearance in front of the trough.

16 gauge galvanized steel, finished gray with plated screws. The zinc coating is what lets it live in a damp-ish indoor environment like a basement switchgear room without surface rust, and 16 gauge keeps a 6 x 6 body from oil-canning when you tug conductors through it.

It is built to CSA C22.2, so it carries Canadian certification for the enclosure. Useful if you are a contractor or institutional buyer standardizing one gutter part number across sites on both sides of the border.

That is a normal use for it. A 6 x 6 x 12 inch screw-cover galvanized trough works as a pull and splice point where several conduits converge, and because it ships with no knockouts you place every entry exactly on your conduit centerlines. Keep your bending space and conductor fill within code for the 6 inch dimension, and remember NEMA 1 limits it to indoor dry locations.

Eaton B-Line catalog number 6612 GTGV NK. Read it as 6 x 6 cross-section, 12 inch length, galvanized trough, screw cover, no knockouts. There is one configuration under that number, so there is no finish or size option to specify.
