B-Line Eaton series imperial cable tray and ladder, 6" Height, 54.0625" Length, 6" Width, Series 2-5 horizontal bend, Aluminum, 90° Angle, 48" Radius

Plan for the full 54-1/16 inch overall length of the fitting. The 6A-06-90HB48 turns on a 48 inch inside radius, and the piece measures 54.0625 inches end to end, so the corner needs that much clear space from the last hanger on each leg before your straight sections pick up again.

Bend radius is driven by the cable, not the tray. Large power and fiber cables have a minimum bending radius that a tight fitting will violate, and the 48 inch radius on the 6A-06-90HB48 is the widest sweep in the common radius range, so it suits heavy MV power feeders and fiber trunks. If you are running small control or instrumentation cable and space is tight, a shorter radius fitting in the same 6 x 6 Series 2-5 aluminum family does the job in less space.

The 6A-06-90HB48 bend is UL Classified. That is the classification aluminum tray carries, and it is the basis on which tray is permitted as an equipment grounding conductor under the NEC when properly bonded across joints. Use listed bonding jumpers at the splice plates on each end of the bend.

Aluminum is the usual choice where weight and corrosion matter. The 6A-06-90HB48 bend is aluminum, which forms its own oxide layer and holds up outdoors and in damp plant areas without galvanizing or paint, and at 18.9 lb the fitting is light enough for one person to place on a trapeze. For heavy mechanical abuse or high point loads, a steel tray system is the tougher choice.
