B-Line Eaton series imperial cable tray and ladder, 4" Height, 25.692" Length, 24" Width, Series 2-5 vertical inside bend, Aluminum, 30° Angle, 36" Ra

A vertical inside bend carries the tray up or down while the cable stays on the inside of the turn, so the tray rises toward the cable side of the elevation change. The B-Line 4A-24-30VI36 is a 30 degree vertical inside bend in the Series 2-5 aluminum ladder tray family, built on a 36 inch radius. If your run changes elevation the other way, with the cable riding the outside of the turn, you need the matching vertical outside bend instead, not this fitting. Horizontal direction changes take a horizontal elbow.

Plan on roughly 25.692 inches of overall length for the 4A-24-30VI36 fitting itself. That is the dimension to deduct from your straight tray when you lay out the elevation change, plus whatever your splice and support spacing requires on each side.

The bend radius has to be at least as large as the minimum bending radius of the largest cable in the tray. The 4A-24-30VI36 is a 36 inch radius fitting, which suits larger power cable where a 12 or 24 inch radius would over-bend the conductor. If your run carries only small control or instrumentation cable, a tighter radius fitting of the same 24 inch width will do the same job in less space.

Aluminum. That is the usual choice for wet, humid, or mildly corrosive environments where painted steel would need coating maintenance, and it keeps the fitting light: the 4A-24-30VI36 weighs 7.082 lb, so one person can set it on the supports. Aluminum tray also has to be bonded and grounded per the installation requirements for your system.

Yes. The 4A-24-30VI36 vertical inside bend is CSA certified, which is what an inspector on a Canadian project will look for on the fitting as well as on the straight tray.

Order the splice plates and hardware separately. The 4A-24-30VI36 is supplied as the bend section itself, so you will need a pair of aluminum splice connectors and bolts at each end to tie it into the adjoining straight tray, plus support hangers sized for a 24 inch wide run.

Quote Eaton B-Line part number 4A-24-30VI36. Reading the number: 4A is the 4 inch aluminum series rail, 24 is the tray width, 30VI is the 30 degree vertical inside bend, and 36 is the bend radius.
