B-Line Eaton series wiring trough, 10" height, 120" length, 10" width, GRTGV NK wiring trough, Embossed thru holes, No knockouts, Screw cover, 3R, Ga

Yes. The 10 x 10 x 120 inch GRTGV NK trough is a NEMA 3R enclosure in galvanized steel, so it is rated for outdoor use against falling rain and sleet. It also carries CSA C22.2 certification. The screw cover is held tight by a flange and plated screws, which is what maintains the 3R seal, so all cover screws need to be installed for the rating to hold.

No. The GRTGV NK version is the no-knockout model, so every conduit entry has to be field drilled or punched. That is deliberate on a 3R outdoor trough, where you only want penetrations where you actually land conduit, and it lets you set hole size and location to suit the run. Plan on a step bit or knockout punch and appropriate raintight fittings.

Mounting is through embossed thru holes in the back of the trough, so it bolts or lags directly to a wall, strut, or backpan. The section is 120 inches long and weighs 84.271 lb empty, before conductors, so plan supports along the full run rather than just at the two ends, and land fasteners into structure or into strut spanning studs.

Screw cover. The full length cover lifts off completely once the plated screws are removed, which makes the whole 120 inch run open for pulling and dressing conductors rather than working through a hinged door. The tradeoff is that frequent access means backing out and reinstalling every screw, so if the trough is a junction point you open weekly, a hinged style is easier to live with.

16 gauge galvanized steel with a gray finish, and plated screws at the cover. The galvanized base plus plated hardware is what suits it to the outdoor 3R application; if the trough is going into a washdown, coastal, or chemical area, a painted or stainless enclosure is the better call.

The interior cross section is 10 inches by 10 inches, which is the usable pulling space; the section runs 120 inches long. NEC wireway fill limits conductors to 20 percent of the interior cross sectional area, so size your bundle against 100 square inches of gross area rather than against the physical room you can see. Splices and taps are additionally limited to 75 percent of the cross section at any point.

The 10 x 10 x 120 inch GRTGV NK section ships as the trough body and screw cover only. Connecting runs, making corners, or closing off an open end takes separate B-Line fittings in the matching 10 x 10 size, and since this is the no-knockout version, any conduit entries are field cut and need their own raintight connectors.
