B-Line Eaton series wiring trough, 4" height, 120" length, 4" width, GGV NK wireway, Thru holes, 39 top knockouts, 39 bottom knockouts, Screw cover,

No. The 44120 GGV wiring trough is a NEMA 1 enclosure, which means indoor, dry locations only, general purpose protection against incidental contact and falling dirt. For an outdoor run you need a NEMA 3R rainproof trough instead. The 44120 GGV is CSA Certified.

It comes punched. The trough has 39 knockouts along the top and 39 along the bottom, so you can drop conduit into it at regular intervals without field drilling. Knockouts stay blanked until you need them.

Screw cover. The cover is secured with plated screws, so pulling it takes a driver and you get a fully removable cover for the whole 120 inch run. If you want tool-free access for frequent pulls, a hinged-cover wireway is the better choice; this one is set up for install-and-close applications.

16 gauge galvanized steel with plated screws, finished gray. The galvanizing gives it corrosion resistance for a plant or garage interior, but it is still a NEMA 1 body, so it is not sealed against dripping water or washdown.

A 4 x 4 inch section like the 44120 GGV suits branch circuit gutter work, control wiring, and short splice runs where conductor count is modest. Once you are combining several large feeders or need room to train heavy THHN without exceeding the 20 percent cross-sectional fill limit for a wireway, move up to a 6 x 6 or 8 x 8 section. Height and width here are both 4 inches.
