B-LINE 6612 GRT NK – Frequently Asked Questions

1) Can the B-Line 6612 GRT NK wiring trough be mounted outdoors?
The Eaton B-Line 6612 GRT NK trough is a NEMA 3R enclosure, so it is built for outdoor use where falling rain, sleet and external ice formation are the concern. It is not a washdown or watertight rating, so keep it off surfaces subject to hose-down or submersion. Steel body, ANSI 61 gray finish.
2) What are the actual inside dimensions of the 6612 GRT wiring trough?
It is a 6 x 6 x 12 inch trough: 6 inch height, 6 inch width, 12 inch length. That is the common 6x6 cross section used for gutter and pull-box runs, in a short 12 inch section.
3) Does this B-Line trough come with knockouts for conduit?
No. The 6612 GRT NK is the NK (no knockouts) version, so every conduit entry has to be punched or hole-sawed in the field. If you want factory knockouts placed for you, order the knockout version of the same GRT series instead. The blank body is the right pick when your conduit layout does not line up with standard KO patterns.
4) How does the cover come off on the 6612 GRT NK, and can I get back in later?
It is a screw cover, not a hinged lid. The cover seats on a flange and is held by plated screws, so you back the screws out to open it and reinstall them to close. Plan on tool access at the face of the trough wherever you mount it.
5) How do I fasten this wiring trough to a wall or strut?
The back of the trough has embossed thru holes for mounting, so it bolts straight to a wall, backboard or strut run without drilling the enclosure. The unit weighs 6.634 lb empty, so standard fasteners sized to the substrate will carry it once conductors are in.
6) What gauge steel is the B-Line 6612 trough, and is it certified?
Body is 16 gauge steel, CSA Certified, finished in ANSI 61 gray. The 16 gauge wall is what keeps a screw-cover trough from oil-canning when you tighten the cover screws down on a flange.
7) What is the exact part number to order this B-Line trough?
Order Eaton B-Line catalog number 6612 GRT NK. The digits describe the size and type: 6 inch by 6 inch cross section, 12 inch length, GRT screw-cover trough, NK for no knockouts.
8) Is a 12 inch trough section long enough to use as a junction or pull point?
For a 6 x 6 cross section, a 12 inch section works well as a tap, splice or pull point between conduit runs rather than as a long gutter. If you need to carry conductors a distance, order longer sections of the same 6x6 GRT family and couple them; the 6612 is the short body in that size.
