B-LINE 121248 GRTGV NK – Frequently Asked Questions

1) Can the B-Line 121248 GRTGV NK wiring trough be used outdoors?
It's built to NEMA 3R, which means it's rain and sleet resistant for outdoor use in non-washdown locations. The body is galvanized steel in gray with a screw-on cover held by a flange and plated screws, so water shedding depends on mounting it in the correct orientation with the cover seam protected. For hosedown or dusty indoor process areas you want a 4 or 12 rated trough instead.
2) Does this wiring trough come with knockouts for conduit?
No. The NK designation means no knockouts, so the sides, ends, and bottom come blank. You cut or punch every conduit entry yourself, which is the usual choice when the conduit layout is field determined. If you'd rather have factory openings, order the knockout version of the GRTGV trough instead.
3) How is the cover secured, and can I get back into the trough after it's wired?
It's a screw cover, not hinged. The cover seats against a flange and is fastened with plated screws, so access means backing out the screws along the full 48 inch length and lifting the cover off. Fine for a pull box or splice gutter you rarely open; if you're in it often, a hinged cover trough is the better pick.
4) How does the B-Line GRTGV trough mount to a wall or strut?
It has embossed thru holes in the body for through-bolting to a wall, backing board, or strut run. No mounting feet or brackets are part of the trough, so provide your own fasteners sized to the substrate. Plan the supports around the weight: the 12 x 12 x 48 body is 43.712 lb empty, before conductors.
5) What gauge steel is the 12 x 12 x 48 wiring trough, and is it heavy enough for a commercial install?
16 gauge galvanized steel throughout, gray finish. That's the standard body thickness for a 12 inch square screw cover gutter and it carries the CSA C22.2 certification, so it's acceptable for commercial and industrial gutter work where a 3R enclosure is specified.
6) Is the 121248 GRTGV NK trough certified for use in Canada?
It's certified to CSA C22.2, so it's acceptable for Canadian installations as well as US commercial work. Cite the model number 121248 GRTGV NK on the submittal along with the NEMA 3R rating.
7) Do I need anything else besides the trough to finish the run?
The trough ships as body plus screw cover with the plated screws. Anything joining sections or closing penetrations is separate: couplings or connectors between 48 inch bodies, conduit hubs or fittings for the entries you punch (the body has no knockouts), and your own mounting hardware for the embossed thru holes. Grounding and bonding means are also field supplied.
