B-Line Eaton series wiring trough, 6" height, 96" length, 6" width, GRT NK wiring trough, Embossed thru holes, No knockouts, Screw cover, 3R, Steel,

The Eaton B-Line 6696 GRT NK trough is a NEMA 3R enclosure, so it is built for outdoor use where falling rain, sleet and external ice formation are the concern. It is not a washdown or hosedown rating, so keep it off locations that see direct pressure spray or submersion. Body is 16 gauge steel finished in ANSI 61 gray.

No. The NK in 6696 GRT NK means no knockouts, so the box arrives with solid sides and you drill or punch your own conduit entries wherever the run lands. That is the point of ordering NK: on an outdoor 3R application you place and seal each entry yourself rather than plugging factory holes. If you want factory knockouts, order the knockout version of the trough instead.

The 6696 GRT NK uses a screw cover, not a hinged lid. The cover is held by a flange plus plated screws, so you back the screws out and lift the cover clear for pulling conductors, then reset it. Plated hardware suits the outdoor 3R application. Budget wall clearance and working room above the trough, since the whole cover has to come off rather than swinging open.

Yes, the 6696 GRT NK carries CSA certification, which is what an inspector on a Canadian job will look for on a wireway or gutter. Combined with the 3R construction, it works for exterior installations on both sides of the border.

The finish is ANSI 61 gray, the standard gray used across commercial switchgear, panelboards and wireway, so a 6 x 6 run in this trough will read as the same family alongside most existing gear. For a property manager standardizing a mechanical room or an exterior wall of disconnects, the 6 x 6 profile is the common size to stay consistent with.

16 gauge is the standard body thickness for commercial screw cover wireway in this size class, and it is what gives the 6696 its rigidity over the 96 inch span. Steel construction also means you can drill your own entries cleanly, which you will be doing since this is the no-knockout version.
