B-LINE 141472 GRT NK – Frequently Asked Questions

1) Can the 14 x 14 x 72 B-Line wiring trough be used outdoors?
NEMA 3R is the rating on the 141472 GRT NK trough, so it is suited to outdoor use where the concern is falling rain, sleet and snow. It is not a washdown or hosedown enclosure. The steel body is finished in ANSI 61 gray and the cover screws are plated, which helps where there is weather exposure.
2) Does this B-Line trough come with knockouts for conduit?
No. The 141472 GRT NK is a no-knockout trough, 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 place the openings to suit the run instead of working around factory locations. If you want factory knockouts, order the knockout version of the GRT trough instead.
3) What size is the B-Line 141472 GRT NK wiring trough?
It is a 14 inch by 14 inch cross section, 72 inches long. That 14 by 14 body gives room for large conductor bundles and pull space at gutter taps; a 6 by 6 or 8 by 8 trough is the usual choice for lighter branch circuit work.
4) How is the cover secured on this Eaton B-Line wiring trough?
It is a screw cover. The cover seats against a flange and is held by plated screws along its length, so you back the screws out to open it rather than swinging a hinged lid. Plan for clearance in front of the trough to lift the cover off, and for a second set of hands on a 72 inch cover.
5) Is this wiring trough approved for use in Canada?
The 141472 GRT NK carries CSA Certification, so it is acceptable for Canadian installations as well as US work. If a submittal calls out a specific NEMA type, note it is rated NEMA 3R.
6) What is the exact part number to order this B-Line 14 inch trough?
Order Eaton B-Line model 141472 GRT NK. The number reads out as the dimensions: 14 inch height, 14 inch width, 72 inch length, GRT screw-cover trough, NK for no knockouts.
