B-LINE 4A-30-LR18 – Frequently Asked Questions

1) What does the Eaton B-Line 4A-30-LR18 reducer actually do in a cable tray run?
It transitions a 30 inch wide aluminum tray down to an 18 inch wide tray, with the reduction taken on the left side. The right side rail stays in line, so the run shifts over as the width steps down. Height is 4 inches, matching a 4 inch deep tray on both sides of the transition.
2) Is this cable tray reducer aluminum or steel, and does that matter for an outdoor or damp run?
Aluminum. That is the usual choice where weight matters or where a steel tray would need galvanizing to survive moisture. If your spec calls for steel or stainless tray, this fitting is not a match for it, since reducers are ordered in the same material and finish as the tray they join.
3) Does the Eaton B-Line 4A-30-LR18 reducer carry any agency listing for a Canadian job?
It carries CSA certification, which is what a Canadian inspector will look for on cable tray components. If your submittal calls out a different listing, verify the spec against that requirement before you commit the run.
4) What is the exact part number to order this B-Line reducer by?
Order it as Eaton B-Line 4A-30-LR18. The number reads out as 4 inch height, aluminum, 30 inch incoming width, left reducer to 18 inch.
5) How heavy is a single 30 to 18 inch aluminum tray reducer for handling and support loading?
About 4.087 lb per fitting. Light enough for one person to set on a ladder, and negligible against the support spacing you will be sizing for cable fill rather than fitting weight.
