NEMA 3R is the rating on the 101036 GRT NK trough, so it handles outdoor rain, sleet and snow in a vertical-mount application. It is not a washdown or hosedown enclosure, and it is not rated for dust-tight or oiltight service. For a wet indoor process area or a location subject to direct spray, you need a 4 or 4X trough instead.

No. The NK in 101036 GRT NK means no knockouts, so every conduit entry is field-drilled or punched where you want it. That is usually what an electrician wants in a gutter run, since it lets you line entries up with the raceway and panel positions on the actual job. If you would rather have factory openings, order a knockout version of the GRT trough instead.

Screw cover. The cover is secured with plated screws all the way around, so you remove hardware to open it rather than swinging a hinge. Plan for access clearance in front of the trough and allow time on installs where you will be pulling the cover repeatedly. If you expect frequent entry, a hinged-cover gutter is the easier choice.

16 gauge steel, finished in ANSI 61 gray, which is the same standard gray used on most commercial panelboards, disconnects and control enclosures. So a run of these troughs reads as part of the same gear lineup rather than standing out. 16 gauge is the usual weight for a gutter this size and keeps the body rigid over a 36 inch span.

It is CSA Certified, which covers submittals on Canadian work and satisfies inspectors who want a recognized mark on the raceway. That is the certification carried on the 101036 GRT NK trough.

A single 101036 GRT NK covers 36 inches. Joining two troughs end to end, or turning a corner, takes separate GRT connectors or fittings, and any conduit entries have to be field-cut because the trough ships with no knockouts. The screws for the cover come with the trough.

It is a wiring trough, also called a gutter or auxiliary gutter: a straight 10 by 10 by 36 inch enclosed steel raceway used for splices, taps and pull space alongside panels, with a removable screw cover the full length. A junction box gives you one point of access; a cable tray is open and supports cable over long spans. Choose the trough when you need continuous access to conductors and a closed, gray-finished enclosure that matches the gear.
