B-LINE 66 HSF – Frequently Asked Questions
1) What size wireway does the B-Line 66 HSF end flange fit?
The 66 HSF end flange is sized for 6 x 6 inch wireway, matching a 6 inch height and 6 inch width. It will not adapt a 4 x 4 or 8 x 8 run; the flange opening has to match the trough cross section it terminates.
2) Is the 66 HSF wireway flange rated for outdoor or wet locations?
No. It is a NEMA 1 (degree of protection 1) part, which is indoor, general purpose only. For outdoor, washdown, or damp locations you need a NEMA 3R or 4 rated raintight wireway and matching flange instead.
3) What is a wireway end flange actually used for?
It closes off the end of a wireway run and provides a bolted flange connection where the trough lands against an enclosure, panel, or box, so conductors pass through a finished, supported opening rather than an open cut end. The 66 HSF handles that on 6 x 6 inch trough.
4) Is the B-Line 66 HSF end flange UL Listed for use in an inspected installation?
Yes, the 66 HSF carries a UL Listing, which is what an inspector looks for on wireway fittings in commercial and institutional work.
5) How much room do I need to allow past the end of the wireway for the 66 HSF flange?
Allow for a length/depth of 7.784 inches on the 66 HSF when laying out the run against a panel or wall, on top of the 6 x 6 inch trough footprint.
6) What part number should I order for a 6x6 B-Line NEMA 1 wireway end flange?
Order Eaton B-Line 66 HSF. That is the manufacturer part number for the 6 x 6 inch, NEMA 1, steel, ANSI 61 gray end flange.
7) Will the gray finish on this B-Line flange match existing wireway on the job?
The 66 HSF is painted ANSI 61 gray, the standard gray used across B-Line screw cover wireway and most industrial panel gear, so it blends with an existing ANSI 61 run. If your trough is white or a custom color, it won't match.
