B-Line Eaton series imperial cable tray and ladder, 6" Height, 51.000" Length, 30" Width, Series 2-5 vertical outside bend, Aluminum, 90° Angle, 48" R

A vertical outside bend carries the tray run over an obstruction or up a wall where the tray turns away from the cable side, so the cables ride on the outside of the curve. The Eaton B-Line 6A-30-90VO48 makes that turn at a full 90 degrees on a 48 inch radius. The large radius is what keeps the cable bend within its allowable limit as it goes around the corner. If your run turns the other way, toward the cable side, you need a vertical inside bend instead, not this fitting.

Plan on 51 inches of overall length for the fitting, which is the dimension B-Line lists for the 6A-30-90VO48. With a 48 inch radius turning a full 90 degrees, the bend projects out roughly that far in each direction, so tight ceiling pockets or close wall offsets are the usual problem. Check the clearance before you commit the hangers.

Radius is driven by the cable, not the tray. Large power and control cables carry a minimum bending radius that a short fitting will violate, and the 48 inch radius on this bend gives the most room of the common options. Smaller radius fittings save space but only suit smaller, more flexible cable. If your cable schedule calls out a minimum bend radius near 48 inches, this is the fitting that satisfies it.

Order Eaton B-Line part 6A-30-90VO48. The number reads out as 6 inch rail, aluminum, 30 inch width, 90 degree vertical outside, 48 inch radius, which is how B-Line codes the Series 2-5 fittings.

The fitting weighs 26.1 lb bare. Aluminum keeps it light enough for two people to set by hand, but with a 51 inch long fitting you still want a hanger on each side of the bend before you load cable into it.

Aluminum construction is the usual pick for wet, outdoor, and chemically aggressive areas because it does not need galvanizing to resist corrosion, and it weighs far less than steel for the same span. This bend is aluminum throughout, so it keeps the run in a single material and avoids dissimilar metal contact at the fitting.
