B-Line Eaton series wireway elbow fitting, Lay-in, 15° elbow, top opening, 12, Steel, Includes zinc plated hardware and latches, 8" X 8"

Yes. The 88-12LE15A is sized for 8 x 8 inch wireway, with a stated 8 inch height and 8 inch width and 5 inch length/depth. It is a 15 degree elbow with a top opening, so it mates to the ends of 8 x 8 lay-in trough of the same NEMA 12 series.

It is built to NEMA 12, which is the enclosure type for indoor protection against falling dirt, circulating dust, lint and dripping non-corrosive liquids. That covers most manufacturing and process floors. It is not a wet-location or washdown rating, so for outdoor runs or hosedown areas you need NEMA 3R or 4 wireway and fittings instead.

No. Zinc plated hardware and latches are included with the elbow, so the cover latches and the connecting hardware come in the box. You supply only the wireway sections themselves and any hangers or supports for the run.

Top opening means the removable cover is on the upper face of the elbow, so you lay conductors in from above rather than pulling them through. That suits a run mounted against a wall or on a horizontal plane where you can reach the top. If your run is turning in a plane where the access face would end up against the wall or ceiling, you want a side-opening elbow instead, not this one.

Yes, the elbow is UL Listed. Keep the whole run in the same NEMA 12 lay-in family so the enclosure rating is not broken at a fitting, which is where inspectors usually look first.

Order Eaton B-Line part number 88-12LE15A. In that designation the 88 is the 8 x 8 inch cross section, 12 is the NEMA 12 rating, and LE15 is the 15 degree lay-in elbow.

Steel construction, 6.4 lb for the 8 x 8 elbow. That weight matters when you are spacing supports on a long run, since the fitting adds to the loaded span along with the conductors.
