B-LINE 4A-30-RR18 – Frequently Asked Questions

1) What does the B-Line 4A-30-RR18 reducer actually do in a cable tray run?
It transitions a 30 inch wide tray down to an 18 inch wide tray, with the reduction taken on the right side so the left side rail stays in a straight line. That matters when you are running along a wall or beam and need the run to keep one edge true while the tray narrows after cable drops out of the run. It is a Series 2-5 right reducer, 4 inch rail height, 14.97 inches long through the transition.
2) Is this cable tray reducer UL Classified?
Yes, the 4A-30-RR18 aluminum reducer is UL Classified. For inspected commercial and industrial installs where the tray run is used as an equipment grounding conductor or has to satisfy the electrical inspector on listed components, that classification is what gets checked.
3) What is the exact part number for the B-Line 30 inch to 18 inch right reducer?
The manufacturer part number is 4A-30-RR18, an Eaton B-Line aluminum right reducer, 4 inch height, transitioning 30 inch tray to 18 inch tray. That is the number to quote when matching an existing run or adding to a submittal package.
