B-Line Eaton series wireway elbow fitting, 2.5" X 2.5" sealing plate kit, Lay-in, 90° elbow, inside opening, 12, Steel, ANSI 61 gray painted

Yes. Model 22-12LE9B is sized 2.5 inches by 2.5 inches, so it mates with 2-1/2 x 2-1/2 inch lay-in wireway trough. It will not adapt between two different trough sizes, so both runs it joins have to be 2-1/2 square.

Inside opening means the cover opening and the turn face toward the inside of the 90 degree corner. Run the trough to the corner and look at which side the removable cover has to stay accessible on: if the cover faces into the angle of the turn, the inside opening elbow is the one you need. An outside opening elbow puts the access on the outer face of the corner. The 22-12LE9B is the inside opening version.

The 22-12LE9B is a NEMA 12 fitting and ships with a sealing plate kit, so it is intended for dust, falling dirt and dripping non-corrosive liquid indoors. NEMA 12 is not a hosedown or wet-location rating, so for washdown duty use NEMA 4 or 4X wireway and fittings instead.

The sealing plate kit is part of the 22-12LE9B. That is what maintains the NEMA 12 seal at the joint between the elbow and the adjoining trough sections, so you do not buy it as an add-on.

Yes, the 22-12LE9B is UL Listed, which is what an inspector looks for on the fitting as well as the trough.

It is painted ANSI 61 gray, the standard gray used on most industrial steel wireway and enclosures, so it will match existing ANSI 61 trough runs. Body is steel.

Plan on 5.94 inches of length/depth at the turn, with a 2.5 by 2.5 inch cross section. It weighs 3.491 lb, so one person can set it and hold it while the sections are bolted up.
