B-Line Eaton series imperial cable tray and ladder, 6" Height, 28.5" Length, 18" Width, Series 2-5 horizontal bend, Aluminum, 45° Angle, 24" Radius

Yes, that is exactly the run it is built for. The 6A-18-45HB24 is an 18 inch wide, 6 inch deep aluminum fitting from the Eaton B-Line Series 2-5 family, so it splices into straight sections of the same 18 inch width and 6 inch side rail height. Width and rail depth both have to match on a tray fitting, and mixing aluminum fittings into a steel run is not the same material class.

It turns on a 24 inch radius. That number is the one to check against your cable bend radius calculation, because the tray fitting cannot turn tighter than the largest conductor in the run allows. Heavy power feeders and larger fiber bundles often call for a wider sweep, so if your cable schedule demands more than 24 inches you need a larger radius bend instead of this one.

A 45 degree horizontal bend is a fitting, not a support point, and it is 28.5 inches long carrying cable through a 24 inch turn. Plan support on both sides of the fitting rather than letting it cantilever off the last hanger of the straight section. Splice plates and hardware to join the bend to the adjacent straight tray are ordered separately from the fitting itself.

It carries a CE marking. That is the one certification on record for the 6A-18-45HB24 aluminum horizontal bend, and it is what goes on the submittal for this fitting.

Order it as Eaton B-Line 6A-18-45HB24. Reading the number: 6 inch rail depth, aluminum, 18 inch width, 45 degree horizontal bend on a 24 inch radius. That is the full identity a distributor needs, and it is the string to match when you are adding to an existing Series 2-5 aluminum run.
