B-Line Eaton series imperial cable tray and ladder, 6" Height, 35.625" Length, 24" Width, Series 2-5 horizontal bend, Aluminum, 30° Angle, 48" Radius

Plan for a 48 inch inside radius on the turn, and the fitting itself measures 35.625 inches along its length. That radius is the key number when you are routing around structure or holding clearance off a wall, and it also sets the bend allowance for the cable pulled through it. Tight ceiling spaces often force a shorter radius fitting instead, so check the turn envelope on the drawing before you commit to 48 inches.

This bend is aluminum, which holds up well outdoors, in damp plants and in corrosive atmospheres without needing galvanizing, and it is light to handle: the fitting weighs 10.7 lb, so one person can set it on the supports. Aluminum also carries less load per span than steel of the same section, so if your run carries heavy power feeders over long support spacing, a steel tray system is usually specified instead.

The 6A-24-30HB48 bend is UL Classified. Aluminum cable tray that carries UL Classification is the basis for using the tray system as an equipment grounding conductor under the NEC, but the classification applies to the tray system assembled per the manufacturer's instructions, including bonding jumpers at fittings where required by the installation. Confirm the grounding method on your electrical drawings.

What you are ordering is the horizontal bend fitting itself, aluminum, 24 inch width with 6 inch side rails. Splice plates, hardware and any supports or hangers at the turn are ordered separately, so add them to the same order if you want the turn to go together in one trip. Cable tray fittings are normally supported on both sides of a bend.

Order Eaton B-Line 6A-24-30HB48. Reading the number: 6 inch rail depth, A for aluminum, 24 inch width, 30 degree horizontal bend, 48 inch radius. Any change in width, rail depth, angle or radius is a different part number, so match all four before releasing the order.
