B-Line Eaton series imperial cable tray and ladder, 6" Height, 9.78" Length, 9" Width, 9" and 6" Tray widths, Series 2-5 right reducer, Aluminum

It's a right-hand reducer fitting that transitions a 9 inch wide tray down to a 6 inch wide tray, in a 6 inch tray height. The offset is on the right side, so the left side rails stay in line and the run steps in only on the right. Model 6A-09-RR06, aluminum construction.

No. The 6A-09-RR06 is specifically a right reducer, meaning the reduction is taken on the right side of the run while the left rail runs straight. For a left-side step you need the corresponding left reducer in the same 9 inch to 6 inch, 6 inch deep configuration. If you want the reduction split evenly across both rails, that's a straight (centered) reducer, again a different part.

Aluminum. It needs to match the tray it is spliced into: mixing aluminum fittings with steel tray puts dissimilar metals in contact at the splice, which is a corrosion concern in damp or outdoor runs. If your straight sections are aluminum Series 2-5 tray, this is the matching material. Finished weight is 2.6 lb, so it's a one-hand fitting to set in place.

It carries the CE marking. That is the only marking published for the 6A-09-RR06 right reducer.

Height 6 inches, width 9 inches, length along the run 9.78 inches, weighing 2.6 lb. The 9 inch width is the wide end; the narrow end lands on 6 inch tray.
