B-Line CABLE SUPPORT FITTING, SERIES 2,3,4&5, 5" / 6" HEIGHT, 9" WIDTH, 48" RADIUS, ALUMINUM

It's a cable support fitting for B-Line ladder cable tray, sized for 9 inch wide tray with a 6 inch height and a 48 inch radius. Fittings like this carry the cable bundle through the turn so the conductors keep their bend radius instead of being pulled over a tray rail. Aluminum construction, and it's listed for Series 2, 3, 4 and 5 tray.

Yes, the 48 inch figure is the radius the fitting holds the cables to as they turn. Large-radius fittings like this get specified where the cable manufacturer's minimum bend radius is large, which is typical of heavy power feeders and large fiber bundles. If your cable spec allows a tighter bend, a smaller radius fitting in the same 9 inch width will take less ceiling space.

Series 2, 3, 4 and 5 B-Line tray. That covers the common aluminum ladder tray loading classes, so you don't need a different fitting part number when the run changes series, only when the width or height changes.

Aluminum keeps the fitting light for overhead work and resists corrosion without plating, which is why it's the usual choice for indoor plant, data center and utility runs. Match it to aluminum tray so you aren't bolting dissimilar metals together in a damp or outdoor location. For runs already built in galvanized or stainless steel tray, order the support fitting in the matching material.

Order it as B-Line 6A-09-CSF48. That's the number to quote for the aluminum 9 inch, 6 inch height, 48 inch radius support fitting.
