B-Line Eaton series imperial cable tray and ladder, 4" Height, 27.000" Length, 36" Width, Series 2-5 vertical outside bend, Aluminum, 90° Angle, 24" R

A vertical outside bend carries a tray run over a rise, changing elevation so the tray bends away from the cable side. The B-Line 4A-36-90VO24 makes that turn at 90 degrees on a 24 inch radius, so the run climbs (or drops) a full quarter turn in one fitting rather than being pieced together. If your elevation change goes the other direction, with the cables on the inside of the curve, you need a vertical inside bend instead, not this part.

Plan on 27 inches of run length for the fitting itself, measured along the depth of the piece, with the curve struck on a 24 inch radius through 90 degrees. On a vertical rise that means the tray needs roughly that much clear space above or below the straight section before any obstruction, ceiling structure, or duct crossing. Tight ceiling plenums are where this gets caught, so check the clearance before the hangers go in.

Order it as Eaton B-Line 4A-36-90VO24. Reading the number: 4A is the 4 inch aluminum side rail, 36 is the tray width, 90VO is the 90 degree vertical outside bend, and 24 is the radius. Distributors cross it by that full string, since the width and radius digits are what separate it from the rest of the Series 2-5 bend family.

It is CE marked. That is the only certification carried on the 4A-36-90VO24 record, so if your submittal package requires a specific listing beyond CE, verify it against the manufacturer's submittal sheet for the Series 2-5 aluminum line.

12.7 lb for the fitting alone. That is the dead load you add at the bend before any cable fill, and it is light enough that standard trapeze or cantilever supports on a 36 inch aluminum run handle it. Cable weight, not the fitting, drives the support spacing.
