B-Line Eaton series wireway elbow fitting, Lay-in, 90° elbow, Sweep elbow, 1, Steel, ANSI 61 gray painted finish, 8" X 8"

Yes. The Eaton B-Line 88 L SWEEP is sized for 8 inch by 8 inch lay-in wireway, with a product height and width of 8 inches each. It turns the run 90 degrees. If your trough is 4 x 4, 6 x 6, or 12 x 12, this is the wrong fitting size.

No. It is a NEMA 1 enclosure rating, which is indoor, general purpose protection against incidental contact and falling dirt only. For a rooftop, washdown area, or anywhere exposed to rain you need a NEMA 3R or 4 rated raintight wireway and matching elbow instead.

A sweep elbow has a curved, large-radius opening instead of a sharp mitered corner, so conductors turn the corner with a gentler bend. That matters when you are pulling large-diameter feeders that would exceed their bend radius in a square corner. The 88 L SWEEP is the sweep version, 90 degrees, with a 12.09 inch length/depth dimension reflecting that extra radius. For light branch-circuit conductors a standard square 90 elbow does the same job in less space.

Yes, it is a lay-in fitting. The cover comes off so wire drops straight into the channel and the cover goes back on, no fishing or pulling through the corner. That is the normal reason a contractor picks a lay-in wireway system over conduit for a panel-to-panel run.

Yes, the 88 L SWEEP elbow is UL Listed. That is the line inspectors look for on a wireway fitting in a commercial or institutional install.

Steel with an ANSI 61 gray painted finish. ANSI 61 gray is the standard finish across Eaton B-Line lay-in wireway and most competing gray wireway lines, so it matches typical existing runs and panel gear. Painted steel is for dry indoor use; it is not stainless and not galvanized.

It weighs 9.068 lb. At roughly nine pounds of painted steel plus the conductors turning through it, plan a hanger or strut support at or near the elbow rather than cantilevering it off the straight sections.
