B-LINE 4A-36-RR18 – Frequently Asked Questions

1) What tray widths does the B-Line 4A-36-RR18 reducer connect?
The Eaton B-Line 4A-36-RR18 is a right reducer that transitions a 36 inch wide cable tray run down to an 18 inch wide run. Both tray widths are called out on the part: 36 inch and 18 inch. It is the right-hand version, meaning the reduction is taken off one side while the opposite side rail stays in line, so the run keeps a straight edge on one side.
2) Should I order a right reducer or a left reducer for my cable tray transition?
It depends which side of the run you want to hold straight. The 4A-36-RR18 is the right-hand reducer: standing and looking along the direction of the run, the offset is taken on the right and the left rail continues in line. If your wall, cable drop, or adjacent tray needs the opposite rail held straight, you want the left reducer instead. A straight (centered) reducer pulls in equally from both sides and is a different fitting again.
3) What is the manufacturer part number for the B-Line 36 inch to 18 inch right reducer?
Order it as 4A-36-RR18 from Eaton's B-Line series. That number reads out as 4 inch aluminum rail, 36 inch nominal width in, right reducer to 18 inch out.
4) What does the 36 x 18 inch aluminum tray reducer weigh for handling and support spacing?
4.6 lb. Aluminum keeps this fitting light enough for one person to set in place overhead, and it adds very little dead load at the support point either side of the transition.
