B-LINE 121236 GRT NK – Frequently Asked Questions

1) Can the B-Line 121236 GRT NK wiring trough be used outdoors?
It's a NEMA 3R rated steel trough, so it's built for outdoor use where rain, sleet and snow are the concern. NEMA 3R is rainproof, not watertight and not dust-tight, so keep it out of washdown areas and off surfaces where water can pool against the cover. The cover screws are plated to hold up in that environment.
2) Does this 12 x 12 x 36 B-Line trough come with knockouts for conduit?
No. The 121236 GRT NK is the NK (no knockouts) version, so every conduit entry has to be punched or drilled in the field. That's what most electricians want on a pull box or gutter run, because you control exactly where the raceway lands. If you'd rather have factory openings, you need the knockout version of the GRT trough instead.
3) How do I mount this trough to a wall or strut?
The back of the enclosure has embossed thru holes, so you bolt straight through the body into your wall, unistrut or backing. No mounting feet or brackets are part of the design, and fasteners are not supplied, so bring hardware sized for your substrate and rated for the 34.24 lb empty weight plus the wire fill.
4) What are the actual inside working dimensions I get with this wiring trough?
The body is 12 inches high, 12 inches wide and 36 inches long, which gives a full square cross section for wire bending space and a three foot run between couplings. Steel is 16 gauge. It weighs 34.24 lb, so figure on two people or a lift for overhead work.
5) How does the cover come off on the GRT trough, and does that matter for access?
Screw cover. The lid is secured with plated screws all around, so it is fully removable rather than hinged. Good for a trough you wire once and close up; if you are opening the gutter regularly for troubleshooting, a hinged cover design saves time because a screw cover means loose hardware in your hand on a ladder.
6) Is the B-Line 121236 GRT NK trough certified for use on a commercial or industrial job?
It is CSA Certified, which is the listing an inspector looks for on an electrical enclosure in Canada and is widely accepted on US commercial work. Order it by manufacturer part number 121236 GRT NK for submittals.
7) Will the finish on this trough match my existing panels and gutter?
The finish is ANSI 61 gray, the standard light gray used on switchgear, panelboards and industrial enclosures, so it lines up with most existing electrical equipment on a wall. If your facility has been standardized on a different color, this one is not painted to match.
8) Is 16 gauge steel heavy enough for a 12 inch trough carrying a lot of conductors?
Yes, 16 gauge is the normal body thickness for a 12 by 12 steel wiring trough of this size and handles the sidewall load of a full gutter without oil-canning, especially with the screw-down cover tying the top edges together. For runs longer than three feet, couple additional 36 inch sections rather than trying to span with one box.
