B-Line Eaton series imperial cable tray and ladder, 4" Height, 90" Length, 36" Width, 36" and 30" Tray widths, Series 2-5 horizontal cross, Aluminum,

The 4A-36-30-HX24 cross joins 36 inch and 30 inch wide tray runs. It is built for Series 2-5 cable tray with a 4 inch side rail height, so every leg coming into the intersection has to be 4 inch deep tray of those widths. If all four of your runs are the same width, this is not the fitting you want.

Aluminum. That keeps the fitting light for overhead work (it weighs 39.96 lb despite spanning 90 inches) and gives it corrosion resistance for damp, coastal, or chemically aggressive environments where plain steel tray would need galvanizing or paint. For matching your run, confirm the straight sections are also aluminum so you are not mixing dissimilar metals at the bolted splice.

Plan support at the intersection, not just on the approaching runs. This fitting measures 90 inches across its longest dimension, is 36 inches wide, and weighs 39.96 lb bare, before any cable load. A four-way intersection carries the fill of every leg meeting there, so hangers or trapeze supports should land close to the fitting on each side rather than letting it span between distant supports.
