B-LINE 66120 GRT NK – Frequently Asked Questions

1) Is the Eaton B-Line 66120 GRT NK wiring trough rated for outdoor use?
It carries a NEMA 3R rating, so it's suited to outdoor locations where rain and falling water are the concern, not washdown or hosedown. The steel body is 16 gauge with plated cover screws and an ANSI 61 gray finish, and the unit is CSA Certified. For direct spray or dust-tight requirements you need a 4 or 12 rated trough instead.
2) Does the 66120 GRT NK trough come with knockouts for conduit?
No knockouts. The 66120 GRT NK ships as a blank body, so every conduit entry gets field-punched where you want it. That is the point of the NK designation. If you would rather not punch holes on site, order a knockout version of the same trough size.
3) How does the cover come off on the 66120 GRT NK, and how is it held on?
It's a screw cover. The cover seats against a flange and is secured with plated screws along its length, so you back the screws out to open the run rather than lifting a hinged lid. Fine for pull boxes and gutter runs you rarely reopen; if you expect frequent access, a hinged-cover trough saves time.
4) Will this trough match the gray on my existing B-Line gutter and panelboards?
The finish is ANSI 61 gray, the standard gray used across most commercial electrical enclosures and panel gear, so it lines up visually with existing ANSI 61 equipment on the same wall.
