B-Line Eaton series wiring trough, 8" height, 48" length, 8" width, GRTGV NK wiring trough, Embossed thru holes, No knockouts, Screw cover, 3R, Galva

It is built as a NEMA 3R enclosure in galvanized steel, so it is suited to outdoor or damp locations where rain and falling dirt are the concern. It is not a watertight or washdown rating, so keep it out of hosedown areas and away from direct spray. The cover is held down by a flange and plated screws, which is what keeps water out of the seam.

It is an 8 x 8 inch trough, 48 inches long. That 8 by 8 cross section is what you size conductor fill and bend space against when you run it as a pull and junction enclosure between panels or gutters.

No. The NK in 8848 GRTGV NK means no knockouts, so every conduit entry gets field drilled or punched exactly where your runs land. That is the version electricians usually want on a custom layout. If you would rather have factory openings, you need the knockout version of the GRTGV trough instead.

It is a screw cover, not a hinged lid. Plated screws pull the cover against a flange all the way around. Plan on clearance in front of the trough to lift the full 48 inch cover off, and budget the time if you expect to open it often for future pulls.

16 gauge galvanized steel, finished gray. The galvanizing is what earns it the outdoor 3R application, and 16 gauge is heavy enough that the 8 x 8 body holds its shape when you are pulling conductors through a 48 inch section.

The 8848 GRTGV NK trough carries CSA C22.2 certification, so it is recognized for installation under Canadian electrical requirements as well as US work.

Yes, if the existing sections are the 8 x 8 GRTGV family. This is the 48 inch length in gray galvanized 16 gauge with a screw cover, so it lines up end to end with other 8 x 8 GRTGV troughs and keeps the same appearance across the run. The difference to watch is the NK suffix: this one ships with no knockouts, so entries will not line up with a punched section unless you drill them.
