B-LINE 66120 GRTGV NK – Frequently Asked Questions

1) Can the B-Line 66120 GRTGV NK wiring trough be used outdoors?
It's a NEMA 3R enclosure in galvanized steel, so it's rated for outdoor use against falling rain and sleet. 3R is not a washdown or hose-down rating, so don't put it where it will be sprayed directly or where dust and oil ingress matter. For those conditions you need a 4 or 12 rated trough instead.
2) Does this trough come with knockouts for conduit, or do I have to drill it?
No knockouts. The 66120 GRTGV NK is the NK (no knockout) version, so every conduit entry gets field punched or drilled where you want it. That's the usual choice when the layout isn't fixed at the shop, but if you want factory holes on set centers you need the knockout version rather than NK.
3) How does the cover come off for pulling wire?
Screw cover. The cover seats on a flange and is held by plated screws, so you back the screws out to open the full length of the trough for the pull and re-fasten after. It's not a hinged or latched cover, so plan on tool access along the run where it's mounted.
4) Is this B-Line trough approved for use on a Canadian job?
The 66120 GRTGV NK carries CSA C22.2 certification, which is the Canadian standard an electrical inspector will look for on an auxiliary gutter or wireway. Have the part number and the 3R rating handy for the submittal.
5) What gauge steel is the B-Line 6x6 wiring trough, and what finish?
16 gauge galvanized steel, finished gray with plated screws. 16 gauge is the standard body weight for a screw cover trough of this size, and the galvanized base plus gray finish is what lets it carry the 3R outdoor rating.
