B-LINE 88120 GRT NK – Frequently Asked Questions

1) Can the Eaton B-Line 88120 GRT NK wiring trough be used outdoors?
It is built to NEMA 3R, so it is rated for outdoor use against rain and falling water in raintight-style applications, not for washdown or dust-tight indoor environments. The steel body is finished in ANSI 61 gray and the cover seals with a flange plus plated screws, which is what keeps water out of the top seam. For a hosedown or dusty interior you want a 4 or 12 rated enclosure instead.
2) Does this 8x8 wiring trough come with knockouts already punched?
No. The 88120 GRT NK is the NK (no knockouts) version, so every side and end comes solid and you punch your own conduit openings where the run actually lands. That is the usual choice when conduit entries do not fall on a standard knockout pattern, or when you want to keep the 3R integrity and place fittings exactly. If you would rather have factory openings, order a knockout version of the same trough rather than this one.
3) What part number do I order for the 8 inch by 8 inch by 10 foot no-knockout screw cover trough?
Order Eaton B-Line 88120 GRT NK. The number reads out as the size: 8 inch by 8 inch cross section, 120 inch length, GRT screw-cover trough, NK for no knockouts. Specify that number when you need the solid-sided version rather than a knockout body.
