B-Line Eaton series wireway elbow fitting, Lay-in, 90° elbow, inside opening, 1 rated, Steel, ANSI 61 gray painted, 12" X 12"

Yes. The Eaton B-Line 1212 FL IN is sized for 12 inch by 12 inch lay-in wireway, with a 12 in height and 12 in length/depth on the body. It turns the run 90 degrees. It will not mate to 4x4, 6x6 or 8x8 trough without a reducer, so match the elbow to the cross section of the wireway you are running.

Inside opening means the elbow turns toward the short side of the corner, the cover and opening face the inside of the 90. On the 1212 FL IN that is the configuration you want when the wireway turns and the access side stays on the inner face of the turn. If your run turns the other way, so the opening lands on the long outside face, you need the outside opening version instead. Standing at the corner looking at the run, check which face you need to lay conductors into before you order.

No. The 1212 FL IN carries a Type 1 degree of protection, which is indoor, general purpose only, protection against incidental contact and falling dirt. It is not rated for rain, washdown, or dust-tight service. For an outdoor run or a wet mechanical room you need a NEMA 3R or 4 rated wireway and fittings, not this one.

It is a lay-in fitting. The cover comes off and conductors drop straight into the corner, so you are not fishing a pull through a 90. That is why lay-in wireway is used for feeder and control gutter work where circuits get added later, the cover comes back off and you lay in another run.

Steel, painted ANSI 61 gray. That is the standard gray used across most industrial gear and wireway, so a run of this elbow will match typical panelboard and enclosure finishes already in a plant or mechanical room. Being painted steel, it is a coated indoor product, not stainless or aluminum, so keep it out of corrosive or wet environments.

It weighs 17.184 lb and measures 16.31 in across the widest point, with 12 in body height and depth. That is enough mass at a 90 that you should land hangers or brackets on both legs close to the corner rather than letting the adjoining wireway sections carry it, especially on an overhead run.
