B-Line Eaton series imperial cable tray and ladder, 4" height, 40.46" length, 42" width, Series 2-5 horizontal bend, 30°, 24" radius, Aluminum

Plan on a 24 inch inside radius and roughly 40.46 inches of overall length through the fitting, with the tray turning 30 degrees in the horizontal plane. On a 42 inch wide tray the outside sweep is considerably wider than the radius alone, so check your ceiling or rack clearance on the outboard side before you set hangers.

The fitting holds a 24 inch inside bend radius, which is what governs how tightly the conductors are forced to turn. Large diameter power cable has a minimum bending radius set by the cable manufacturer and by code; if that figure exceeds 24 inches, step up to a larger radius fitting rather than forcing the cable through this one. For control, instrumentation and most feeder sizes, 24 inches is generous.

Aluminum is the reason this fitting weighs 8.966 lb in a 42 inch width, which is why a single installer can set it on hangers. It also holds up in damp and corrosive areas without a coating to maintain. Steel is the choice where you need higher load capacity or where you are matching an existing galvanized steel run, since mixing materials at a splice is something most specs will not allow.

The 4A-42-30HB24 ships as the bend fitting itself. Splice plates, connection hardware and the hangers or trapeze supports on each side of the turn are ordered separately, and both ends of a bend generally need support close in per the tray manufacturer's support rules. Budget those into the order so the crew is not short on the day.

Order by MPN 4A-42-30HB24. The number reads out as 4 inch aluminum, 42 inch width, 30 degree horizontal bend, 24 inch radius, which matches the stated specs exactly. If your drawing calls for a different angle or radius in the same family, only the trailing digits change, so check those two before releasing the order.

CE marked. That is the certification stated for this aluminum Series 2-5 horizontal bend; if your project spec calls for a specific listing beyond that, confirm it against the submittal package for the full tray system rather than the fitting alone.
