B-LINE 121248 GRT NK – Frequently Asked Questions

1) Can the B-Line 121248 GRT NK wiring trough be used outdoors?
It is built to NEMA 3R, so it is rated for outdoor use against falling rain and sleet. Steel body finished in ANSI 61 gray with a screw-on cover secured by flange and plated screws. It is not a watertight or washdown enclosure, so keep it out of locations where it would be hosed down or submerged.
2) Does this B-Line GRT trough come with knockouts for conduit?
No. The NK designation means no knockouts, so every conduit entry has to be field punched or hole sawed where you want it. That is the point of the NK version, you locate openings to suit the run instead of working around factory knockouts. If you would rather have preformed openings, order a knockout version of the GRT trough instead.
3) How does the cover come off for pulling wire?
It is a screw cover, held on by the flange and plated screws. You back the screws out to take the full length of the cover off, which opens the whole 48 inch run for laying in conductors. It is not a hinged or quick-release lid, so budget time for the screws on every access.
4) How is this wiring trough mounted to a wall or strut?
Mounting is through embossed thru holes in the trough body, so it bolts directly to a wall, backboard or strut without drilling the enclosure. Fasteners are not part of the trough, pick anchors rated for the 43.712 lb empty weight plus the conductors you are filling it with.
5) Is this trough listed or certified for a commercial job spec?
The 121248 GRT NK is CSA Certified. Combined with the NEMA 3R construction and 16 gauge steel body, that covers most commercial and industrial gutter specs calling for a certified outdoor-rated wiring trough.
6) What is the part number to order this 12 inch by 48 inch Eaton B-Line trough?
Order it by manufacturer number 121248 GRT NK from Eaton's B-Line series. The number reads as the size and type: 12 inch height, 12 inch width, 48 inch length, GRT screw cover trough, NK for no knockouts.
