B-Line Eaton series wiring trough, 10" height, 24" length, 10" width, GRT NK wiring trough, Embossed thru holes, No knockouts, Screw cover, 3R, Steel

It carries a NEMA 3R rating, so it's built for outdoor use where rain, sleet and snow are the concern. 3R is a rainproof enclosure, not a watertight or washdown one, so keep it out of locations subject to hose-down or submersion. The steel body is finished in ANSI 61 gray and the unit is CSA Certified.

The trough is 10 in high by 10 in wide by 24 in long. That 10 by 10 cross section gives a large gutter area for splices and pulls, which is why it's a common choice ahead of panelboards and multi-meter stacks where a 4 x 4 or 6 x 6 gutter runs out of room. Note the figures are the product dimensions, so allow for the sheet metal and cover flange when you're calculating tight conductor bends.

No. The NK in 101024 GRT NK means no knockouts, so every conduit entry has to be field punched or hole sawed. That's the point of the NK version: you place the penetrations exactly where your raceway lands instead of working around a factory pattern. Plan on a punch set or step bit for 16 gauge steel, and use the correct fittings to keep the NEMA 3R integrity at each new opening.

Screw cover, secured with plated screws. You'll need a driver every time you open it, so it isn't a quick-access enclosure for equipment you service daily. For frequent access, look for a hinged cover trough instead. The screw cover is the standard choice for wire gutters that get opened once at install and rarely after.

It's 16 gauge steel, which is the usual body thickness for commercial screw cover wire troughs of this size and holds its shape when you're pulling large conductors through it. Combined with the ANSI 61 gray finish and CSA Certification, it's specified for standard commercial and industrial gutter runs.

Order Eaton B-Line 101024 GRT NK. The number reads out as 10 in high, 10 in wide, 24 in long, GRT screw cover trough, NK for no knockouts. If your job needs factory knockouts, that is a different suffix, so check the NK before you release the order.

The finish is ANSI 61 gray, the standard gray used across most commercial switchgear, panelboards and enclosures, so it lines up visually with existing equipment in a typical electrical room. That matters for institutional and MRO buyers standardizing an entire facility on one color.
