B-LINE 8872 GRTGV NK – Frequently Asked Questions

1) Can the Eaton B-Line 8872 GRTGV NK wiring trough be used outdoors?
It's built to NEMA 3R, so it handles outdoor use where falling rain, sleet and external ice formation are the concern. The body is galvanized steel at 16 gauge in gray, and the screw cover seals against a flange with plated screws. NEMA 3R is not a washdown or dust-tight rating, so for hose-down or heavy dust locations you want a 4 or 12 enclosure instead.
2) Does this B-Line wiring trough come with knockouts?
No. The NK in 8872 GRTGV NK means no knockouts, so every entry has to be field drilled or punched to suit your conduit. That's the point of the NK version: you decide hole size and placement instead of working around a factory pattern. If you'd rather not punch holes on site, order the knockout version of the same trough.
3) How does the 8872 GRTGV NK trough mount to a wall or strut?
The back has embossed thru holes for fasteners, so it bolts directly to a wall, backboard or strut run. Mounting hardware and anchors are sized to your surface and are not part of the trough. At 41.859 lb for the 72 inch body before any wire goes in, plan anchors and spacing for the loaded weight, and get a second set of hands on the lift.
4) Is this a screw cover trough or a hinged cover?
Screw cover. The lid is held by a flange and plated screws, which means a full cover removal for any pull rather than swinging it open. That's fine for a trough you open rarely, like a feeder pull box. If crews will be in and out of it regularly for adds and changes, a hinged cover version saves a lot of screw handling.
5) Is the 8872 GRTGV NK trough listed for Canadian jobs?
It carries CSA C22.2, so it can be specified on Canadian work as well as US. That matters on cross-border institutional and industrial specs where the enclosure schedule calls out a CSA reference.
6) Is 16 gauge heavy enough for an exposed industrial wireway run?
16 gauge galvanized steel is the standard body thickness for gutter and trough of this size and it takes the handling an exposed mechanical room or exterior wall run puts on it. Galvanized with a gray finish also means you aren't repainting cut edges the way you would with plain steel. For corrosive or coastal environments, step up to a stainless or coated enclosure instead.
