B-Line Eaton series wiring trough, 6" height, 36" length, 6" width, GRTGV NK wiring trough, Embossed thru holes, No knockouts, Screw cover, 3R, Galva

The 6636 GRTGV NK trough is a NEMA 3R enclosure in galvanized steel, so it is built for outdoor use where falling rain and sleet are the concern. It is not a washdown or hosedown rating, so keep it off surfaces that get pressure washed and out of direct spray. The screw cover seats against a flange with plated screws to keep water out at the seam.

It is a 6 inch by 6 inch cross section, 36 inches long. The 6x6 body is the common size for feeder pulls and gutter runs where a 4x4 gets tight, and the 36 inch length is the standard stock length that lines up with most panel and disconnect groupings.

No. The NK in the part number means no knockouts, so the body and end plates come solid. You drill or punch your own openings exactly where the conduit lands, which is why electricians spec NK on custom runs. If you want factory knockouts, you need the knockout version instead of the NK.

It is a screw cover, not a hinged one. The cover sits on a flange and is held by plated screws, so you back the screws out to open the full 36 inch length for the pull and reinstall them after. Plan on access room along one full face when you lay out the mounting.

It carries CSA C22.2 certification, so it can be specified on Canadian work as well as US installs.

Yes, troughs of the same cross section are joined end to end to make longer runs, and at 6 x 6 the 6636 mates with other 6 x 6 GRTGV bodies. Since it ships with no knockouts, you make the connecting opening yourself in the end plates to match the coupling hardware you use.

16 gauge steel, galvanized, with a gray finish and plated screws. The galvanized base is what carries the 3R outdoor rating; gray is the standard color match for panelboards and gutter runs on the same wall.
