B-Line Eaton series wireway elbow fitting, Lay-in, 45° elbow, inside opening, 12 rated, Steel

Model 126-12LE45B is a 45 degree lay-in elbow measuring 12 in wide, 6 in high and 5.04 in deep, so it lands on a 12 in run of the same B-Line Eaton series lay-in wireway. Match the body dimensions of the trough you are running before ordering, since a fitting that does not match the cross section will not bolt up or seal.

The 126-12LE45B is the inside opening version, meaning the hinged cover and lay-in opening face the inside of the turn. Pick it when the run's covers are on the inner face of the 45 degree bend. If your covers fall on the outer face of the turn, you need the outside opening elbow instead, otherwise the fitting's access opening will point the wrong way and you lose lay-in access at the corner.

It carries a NEMA 12 rating, which covers indoor use against falling dirt, circulating dust, lint, and dripping non-corrosive liquids. That suits a manufacturing floor, warehouse, or mechanical room. It is not a wet-location or outdoor rating, so for an exterior run or washdown area you want a NEMA 3R or 4 wireway system instead. The fitting is also UL Listed.

Yes. It is a lay-in fitting, so the cover comes off and conductors drop straight into the corner rather than being pulled around the 45 degree bend. That is the reason to use a fitting at a direction change instead of bending conduit, and it is what makes future adds or re-pulls practical at the turn.

The body is steel. Steel construction gives you the mechanical strength for a supported horizontal or vertical run and bonds as part of the raceway system, and it takes a field touch-up or paint coat where a job spec calls for a color match.

It weighs 8.8 lb. That is a one-hand-and-a-ladder piece for most installers, but the corner still needs to be supported like the rest of the raceway rather than hung off the adjoining trough sections alone.
