B-LINE 4A-36-LR12 – Frequently Asked Questions

1) What does the B-Line 4A-36-LR12 reducer actually do in a cable tray run?
It transitions a 36 inch wide tray down to a 12 inch wide tray, with the reduction taken on the left side. Because it is a left reducer, one side rail stays in line and the offset happens on the other, so the run keeps a straight reference edge. Rail height is 4 inches and the fitting measures 21.91 inches in length.
2) What bend radius does this 36 inch to 12 inch cable tray reducer give me for cable bending?
12 inch radius. That matters because the reducer's radius sets the minimum sweep your conductors take through the transition, so check your cable's minimum bending radius against 12 inches before you commit to this fitting.
3) Is this Eaton B-Line cable tray reducer UL listed for an inspected commercial job?
The 4A-36-LR12 reducer is UL Classified. That is the designation carried on the fitting itself; if your drawing calls out a specific classification detail, match it to the tray system the fitting is being spliced into.
4) How much space do I need in the run to fit the B-Line 4A-36-LR12 reducer?
Allow 21.91 inches of straight run length for the fitting, with the wide end at 36 inches across. Add support on both sides of the transition per your tray support spacing; reducers are a change in section and should not be left hanging between distant hangers.
5) What part number do I order for a 36 to 12 inch left reducer in 4 inch aluminum tray?
Order Eaton B-Line 4A-36-LR12. That number breaks down to 4 inch height, aluminum, 36 inch wide end, left reducer, 12 inch radius.
