B-LINE 66-12LAFW – Frequently Asked Questions

1) What does the B-Line 66-12LAFW adapter actually connect?
The Eaton B-Line 66-12LAFW is a wireway transition piece that takes a lay-in wireway run into a feed-through wireway run. It is built for 6 x 6 inch wireway, so both sides of the transition have to be 6 inch square trough. It ships with one sealing plate kit and one gasket kit so the joint keeps its NEMA 12 rating.
2) Will the 66-12LAFW adapter fit my 4x4 or 8x8 wireway?
No. The 66-12LAFW is sized for 6 x 6 inch wireway only, measured 6 inches high by 6 inches wide, with an overall length of 11.94 inches. For a 4x4 or 8x8 run you need the adapter built for that trough size.
3) Is this wireway adapter rated for a dusty or oily plant environment?
It is a NEMA 12 adapter, which covers indoor use against falling dirt, circulating dust, lint and dripping non-corrosive liquids. It is UL Listed. The included gasket kit and sealing plate kit are what let the transition hold that rating, so both have to be installed, not left in the box.
4) Do I need to buy gaskets and a sealing plate separately for this adapter?
No, both come with it. The 66-12LAFW includes one sealing plate kit and one gasket kit in the box. Fasteners for the wireway run itself and any hardware your trough sections use are a separate matter.
5) What is the exact part number to order this 6x6 lay-in to feed-through wireway adapter?
Order Eaton B-Line 66-12LAFW. That is the manufacturer part number for the 6 x 6 inch NEMA 12 steel adapter in ANSI 61 gray.
6) Will the finish on this adapter match the rest of my Eaton B-Line wireway run?
It is painted ANSI 61 gray over steel, which is the standard gray used across B-Line wireway and most industrial enclosure lines, so it blends with a typical existing run. If your wireway is a custom color or white, it will not match.
