B-LINE 121272 GRT NK – Frequently Asked Questions

1) Can the B-Line 121272 GRT NK wiring trough be used outdoors?
NEMA 3R is the rating on the 121272 GRT NK trough, so it is suited to outdoor locations where falling rain, sleet and snow are the concern. It is not a watertight or washdown enclosure, so keep it off surfaces subject to hose-directed water or dust-laden air. Steel body finished in ANSI 61 gray.
2) Does this wiring trough come with knockouts already punched?
No. The NK in 121272 GRT NK means no knockouts, so every conduit entry gets field-punched or drilled where your run actually lands. If you want factory knockouts, order the knockout version of the GRT trough instead.
3) How does the 121272 trough mount to a wall, and what do I need to support it?
Mounting is through embossed thru holes in the back of the body, so it hangs on your fasteners with no separate mounting bracket kit. At 62.655 lb empty before any conductors, land the fasteners in studs, strut, or masonry anchors rated for the loaded weight, not drywall alone.
4) How is the cover attached on the B-Line GRT screw cover trough?
It is a screw cover design: the cover seats on a flange and is held by plated screws. That means removing the cover is a full unscrew, not a hinge swing, so allow clear space along the whole 72 inch length for cover removal during pulls and future service.
5) Is this trough acceptable for a job that requires third-party listed enclosures?
The 121272 GRT NK trough is CSA Certified. Confirm that satisfies the authority having jurisdiction on your project, since some specs call out a specific listing body for enclosures.
6) What part number do I order for the 12x12x72 no-knockout screw cover trough?
Eaton B-Line part number 121272 GRT NK. The number reads out as the dimensions: 12 inch height, 12 inch width, 72 inch length, GRT screw cover trough, NK for no knockouts.
7) Will the ANSI 61 gray finish match the rest of my gear in a switchgear room?
Yes, ANSI 61 gray is the standard equipment gray used across panelboards, switchgear and enclosures, so a run of these troughs blends with existing distribution equipment instead of standing out. Useful for facility and MRO buyers standardizing a whole electrical room.
