B-LINE 121236 GRTGV NK – Frequently Asked Questions

1) Can the B-Line 121236 GRTGV NK wiring trough be used outdoors?
It carries a NEMA 3R rating, so it's built for outdoor use against falling rain and sleet, in galvanized steel with a gray finish. It is not a watertight or washdown enclosure, so keep it off surfaces subject to hose-down or submersion.
2) What size is the 121236 GRTGV NK trough and how much wire fill does that give me?
Cross section is 12 inches by 12 inches, with a 36 inch run length. That 144 square inch interior is what you work from when you size conductor fill and bend space for a pull or splice box application.
3) Does this Eaton B-Line trough come with knockouts already punched?
No. The NK in 121236 GRTGV NK means no knockouts, so every conduit entry gets field punched or hole sawed where you want it. That's the version electricians pick when the conduit layout doesn't match a factory pattern. If you'd rather have pre-punched entries, order a knockout version instead.
4) How do I mount a 12 x 12 x 36 wiring trough to a wall or strut?
The body has embossed thru holes in the back for fastening straight to the mounting surface or to strut. Fasteners aren't part of the trough, so pick anchors rated for the substrate and for the 34.24 lb empty weight plus whatever conductor fill you add.
5) How does the cover come off on the B-Line GRTGV trough, and can I get back in later?
It's a screw cover, held by a flange and plated screws around the perimeter. Fully removable for pulling and landing conductors, and it goes back on with the same screws for later access. A hinged cover it is not, so plan for somewhere to set the lid during the pull.
6) What gauge steel is the B-Line 121236 GRTGV NK made from?
16 gauge galvanized steel. That's the weight that keeps a 36 inch span from oil-canning when the cover comes off, and the galvanizing is what supports the outdoor 3R rating rather than a painted finish.
7) Is this wiring trough approved for use on a Canadian job?
The 121236 GRTGV NK is certified to CSA C22.2, so it's acceptable for Canadian electrical work under that standard. Worth noting for inspectors and for spec packages that call out CSA rather than a US-only listing.
8) Can I join two of these troughs together for a longer run?
Troughs of the same 12 x 12 cross section butt together end to end to extend a run, and with no knockouts you cut the connecting openings yourself to suit the coupling or connector you're using. Order matching 12 x 12 sections so the interiors line up and the covers sit flush.
9) How many people does it take to hang a 36 inch B-Line trough?
Empty, it's 34.24 lb in a 36 inch length, which is a two-hand lift and realistically a two-person hang once you're working overhead and holding it against layout marks. Set your mounting hardware first, then lift once.
