B-LINE 121272 GRTGV NK – Frequently Asked Questions
1) Does this wiring trough come with knockouts, or do I have to drill my own entries?
The NK in 121272 GRTGV NK means no knockouts. The body and cover come blank, so every conduit entry gets laid out and punched on site to suit your run. That is the version most panel shops and industrial electricians want when conduit entries don't fall on a standard pattern, but if you were expecting factory end and side knockouts you need the knockout version instead.
2) How does the cover attach on the B-Line GRTGV trough, and can I get back into it after wiring?
The cover is a screw cover, held by a flange and plated screws. Back the screws out and the full 72 inch cover lifts off, so the whole wire run is open for pulling, splicing, or adding circuits later. It is not a hinged or latched lid, so allow clearance above or in front of the trough for the cover to come away, and keep the screws with the job.
3) Is the 121272 GRTGV trough heavy enough gauge for an industrial plant, and what is the finish?
Body and cover are 16 gauge steel in a gray finish, which is the standard weight for indoor industrial and commercial gutter work and stiff enough to stay straight over the 72 inch length. Gray paint matches typical panel and enclosure work, so it blends with switchgear and control cabinets on the same wall.
4) Is this Eaton B-Line trough approved for use on a Canadian job?
It's certified to CSA C22.2, which is the Canadian standard family for electrical enclosures, so it can be specified on work inspected to the Canadian Electrical Code. That is the only certification carried on the 121272 GRTGV NK.
