B-Line Eaton series imperial cable tray and ladder, 4" Height, 32.625" Length, 12" Width, Series 2-5 horizontal bend, Aluminum, 30° Angle, 48" Radius

Yes. The 4A-12-30HB48 is built for a 12 inch tray width and a 4 inch side rail height, in aluminum, so it drops into an existing aluminum Series 2 through 5 ladder run of the same width and depth. Match the width and rail height on the straight sections before ordering, since a bend of the wrong rail height will not splice flush.

The fitting is UL Classified. Cable tray is UL Classified rather than UL Listed because the classification covers its use as an equipment grounding conductor and its load class, which is why inspectors look for the classification marking on aluminum tray runs used for grounding continuity.

Order splice plates and hardware separately. The 4A-12-30HB48 is the bend section itself, weighing 7.919 lb, and it needs a pair of splice connectors at each end to join the adjacent straight sections, plus supports sized to your span and load class. Count two splice sets per bend when you build the bill of material.

Order Eaton B-Line part 4A-12-30HB48. The number reads as 4 inch aluminum rail, 12 inch width, 30 degree horizontal bend, 48 inch radius, which is the whole specification a distributor needs to confirm the item without a drawing.

This bend is aluminum, which is the usual pick for outdoor, coastal, wastewater, and food-processing runs because it resists corrosion without coating and weighs far less than steel, making overhead handling easier for a single installer. Steel tray is chosen where higher load capacity per support span matters more than weight or corrosion. Do not mix aluminum and steel in the same run without addressing dissimilar metal contact at the splices.
