B-Line Eaton series wiring trough, 10" height, 72" length, 10" width, GRTGV NK wiring trough, Embossed thru holes, No knockouts, Screw cover, 3R, Gal

It carries a NEMA 3R rating, so it's built for outdoor use where falling rain and sleet are the concern. Rainproof, not watertight and not dust-tight, so keep it out of washdown areas and off surfaces where water can pool against the cover. The galvanized steel body and plated cover screws are what make the outdoor rating hold up.

No. The NK in 101072 GRTGV NK means no knockouts, so every conduit entry gets field-punched or hole-sawed where you need it. That's the version you want when the conduit layout is yours to set. If you'd rather have factory openings on the sides and ends, order a knockout version of the same GRTGV size instead.

It's a 10 inch by 10 inch cross section, 72 inches long. Sizing conductors is a code calculation, not a catalog spec: NEC limits wireway fill to 20 percent of the interior cross-sectional area, and derating applies once you exceed 30 current-carrying conductors. Run that against the 10 x 10 section for your wire sizes.

Screw cover, not hinged. The cover seats against a flange and is held by plated screws along its length, so pulling it means backing out every screw and lifting the whole panel clear. Plan for access room above the trough, and count on the cover being off for the duration of the pull rather than swinging out of the way.

It's certified to CSA C22.2, so it satisfies Canadian electrical enclosure certification requirements for submittal. The exact part to reference on the drawing is Eaton B-Line 101072 GRTGV NK.

A 72 inch section gets you six feet of raceway; coupling two sections end to end takes a connector kit plus the field-cut openings, since this version ships with no knockouts. Closure plates or end plates also get ordered separately if you're not butting the ends up to panels. The trough itself arrives as the body, the screw cover, and its plated screws.

16 gauge galvanized steel is the standard commercial body thickness for troughs this size and it's what gives a 72 inch length its rigidity. In a plant or shop where carts and ladders come near it, support it at both ends and mid-span if you can, and keep the fasteners in structure. The galvanized finish in gray handles damp and unheated spaces better than painted-only enclosures.
