B-LINE 4A-30-SR18 – Frequently Asked Questions

1) What tray widths does the B-Line 4A-30-SR18 straight reducer connect?
The 4A-30-SR18 is a straight reducer that transitions a 30 inch wide cable tray run down to an 18 inch wide run. Both ends are sized for those two widths, so it drops between a 30 inch section and an 18 inch section without any field fabrication.
2) I need to drop from 30 inch tray to 18 inch tray in a data room, what exact part do I order?
Order B-Line part 4A-30-SR18. It is the aluminum straight reducer for a 30 inch to 18 inch transition at 4 inch tray depth, 11.5 inches long, weighing 3.7 pounds. One piece handles the whole transition; splice hardware for the joints is ordered separately with the tray.
3) How much length does a 30 to 18 inch straight reducer add to a cable tray run?
Plan for 11.5 inches of run length. That is the laid-in dimension of the 4A-30-SR18 reducer between the two tray sections, so subtract it when you cut or order the straight lengths on either side of the transition.
4) Is the B-Line 4A-30-SR18 reducer aluminum or steel?
Aluminum. That keeps the piece light at 3.7 pounds, which matters when you are setting it overhead on trapeze hangers, and it suits runs where the rest of the tray is aluminum. Mixing aluminum fittings into a galvanized steel run is a job-spec decision, so match the material to the tray series you already have installed.
