B-LINE 44-12FN3 – Frequently Asked Questions
1) What is a wireway nipple section used for on a 4x4 wireway run?
The Eaton B-Line 44-12FN3 is a short feed-through nipple that joins two 4 x 4 inch wireway sections or ties a wireway to an adjacent enclosure, letting conductors pass straight through between them. It is a feed-through wiring method, so it carries wire from one side to the other rather than providing a pull or tap point.
2) Will the B-Line 44-12FN3 nipple mate with 4 inch by 4 inch wireway?
Yes. The nipple measures 4 inches wide by 4 inches high, matching a standard 4 x 4 wireway cross section, with an overall length/depth of 2.938 inches. If your trough is 6 x 6 or larger, this piece will not line up and you need a nipple sized to that cross section.
3) Is this wireway nipple rated for a washdown or dusty industrial area?
The 44-12FN3 is NEMA 12 rated, which covers indoor protection against dust, falling dirt and dripping non-corrosive liquids. That suits a plant floor, mechanical room or food-adjacent dry area. It is not a NEMA 3R or 4X part, so do not use it outdoors or where it will be hosed down.
4) Is the B-Line 44-12FN3 nipple UL Listed for inspection sign-off?
Yes, it is UL Listed, which is what most AHJs want to see on a wireway fitting during rough-in inspection.
5) Is this nipple steel or aluminum?
Steel construction, which is the usual match for painted steel NEMA 12 wireway. If your run is aluminum or stainless for corrosion reasons, pair it with a nipple in the same material rather than this one.
6) Do I need a feed-through nipple or a pull box between two wireway runs?
Use a feed-through nipple like the 44-12FN3 when conductors simply pass from one 4 x 4 trough into the next and you need no splice or redirection. If you have to pull conductors around a corner, splice, or land taps, a pull or junction box gives you the wire-bending room a 2.938 inch nipple does not.
