B-Line Eaton series wiring trough, 6" height, 6" length, 12" width, 12LW wireway, Wireway hanger, Hinged cover, 12, Steel, Oil-resistant gasket, Hing

Yes. The Eaton B-Line 12606-12LW is a NEMA 12 wiring trough, and the seal comes from an oil-resistant gasket at the cover. That is the rating you want for indoor industrial areas with falling dirt, dust, dripping non-corrosive liquids and coolant mist. It is not a wet-location or washdown enclosure, so if the run is outdoors or gets hosed down, specify a NEMA 3R or 4 trough instead.

Published dimensions are 6 in height, 12 in width and 6 in length/depth. Treat that as a short 6 inch section rather than a full length of trough, so plan on multiple pieces plus connectors for a long run and use the 6 x 12 cross-section when you calculate conduit and wire fill.

It is a 6 in by 12 in cross-section section, part of the 12LW wireway line, ordered as model 12606-12LW. If your drawing calls for 12 x 12 trough you need a different section, because the fill capacity and the connector openings will not match a 6 x 12 body.

Yes. The cover is hinged, held by butt hinges with quick-release latches, so it swings open for pulls and terminations and a tech working overhead does not have to balance a loose cover or chase screws. The latches also let the cover come off entirely when you need clear access to the trough.

It is set up for wireway hanger mounting, meaning it is supported off the hangers rather than bolted flat to a wall. The section weighs 6.962 lb on its own, so size supports for that plus the conductor fill. Hangers are a separate item; nothing in the trough section replaces them.

14 gauge steel, finished in ANSI 61 gray. That is the standard commercial-industrial body thickness for wireway, and ANSI 61 gray matches the typical panelboard and control enclosure finish, so a run of it blends with the switchgear already on the wall.

Certification is to CSA C22.2, so it is acceptable for Canadian electrical work as well as US installations. Inspectors asking for the CSA mark on a wiring trough will find it on this one.

Pick hinged when the trough gets opened repeatedly, for example a control room feeder run or a panel where circuits change. The butt hinges and quick-release latches cut the time to open and there are no cover screws to lose. A screw-cover trough makes more sense where the run is sealed up once and never touched, or where you want the cover harder to open in a public area. The NEMA 12 rating here comes from the gasketed cover, so keep the latches fully engaged to maintain it.
