B-Line 88-12LAFW Eaton series wireway system adapter, Includes (1) sealing plate kit and (1) gasket kit, Lay-in to feed through, Adapter, NEMA 12, Steel, ANSI 61 gray painted, 8" X 8"

It transitions an 8 x 8 inch lay-in wireway run to an 8 x 8 inch feed-through wireway run. Both openings are 8 inches square (8 in height, 8 in width), and the body runs 11.94 inches in length, so it splices into a run rather than terminating it. The adapter ships with one sealing plate kit and one gasket kit so the joint can be closed up to the NEMA 12 rating.

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. NEMA 12 is not a washdown or outdoor rating, so if the run is exposed to hosedown or weather you need a NEMA 4 or 4X wireway system instead.

No. This adapter is built for 8 x 8 inch wireway, 8 inches high by 8 inches wide at the openings. A 6 x 6 or 12 x 12 run needs the adapter sized to that cross section; the sealing plate and gasket kit supplied here will not close a different size opening.

No. One gasket kit and one sealing plate kit come with the adapter, so the sealing hardware for the transition is in the box. Conduit or cable entries you cut into the wireway elsewhere still need their own NEMA 12 rated fittings.

Order it as Eaton B-Line 88-12LAFW. That single manufacturer part number covers the complete adapter with both the sealing plate kit and the gasket kit included, so there is no separate accessory line to add for the seal.

The adapter is painted ANSI 61 gray, the standard gray used across industrial enclosures and wireway, so it matches typical gray-painted steel wireway in a plant or electrical room. The body is steel, not aluminum or stainless.

It weighs 11.583 lb on its own, before conductors. At that weight, in an 11.94 inch long section, most installers land a hanger or bracket near the transition rather than letting the joint carry the run unsupported.
