B-Line Eaton series imperial cable tray and ladder, 6" Height, 33" Length, 12" Width, Series 2-5 horizontal cross, Aluminum, 24" Radius

It is the four-way fitting that joins two straight cable tray runs crossing each other in the same horizontal plane. The 6A-12-HX24 is a Series 2-5 horizontal cross in aluminum, built for 12 inch wide, 6 inch deep tray, with a 24 inch radius on the turns so cable bend radius is maintained through the intersection.

Plan for a 33 inch overall dimension on the fitting footprint, which is what the 24 inch radius plus the 12 inch tray width works out to. In practice that means the intersection needs roughly a 33 inch square clear zone in the ceiling or on the rack before you account for hangers and trapeze supports on each of the four legs.

Bend radius is driven by the cable, not the tray. Large power and fiber cables carry a minimum bending radius, and a 24 inch radius fitting gives that room through the turn so conductors are not kinked where the runs intersect. If your cable allows a tighter bend, B-Line builds the same Series 2-5 horizontal cross in smaller radii; if you are pulling large feeders or fiber, the 24 inch is the one to spec.

It weighs 37.4 lb bare, before any cable. Aluminum keeps it light enough for a two-man lift into a ceiling, but the intersection still wants a support on each of the four legs near the fitting, because the cross concentrates load from four directions at one point.

Aluminum is the usual pick where weight and corrosion resistance matter, indoor plant, data centers, coastal or damp environments, and it is easier to handle overhead. Steel tray is chosen where load spans are long or where physical abuse is expected. The 6A-12-HX24 cross is aluminum, so it should be run with aluminum tray and fittings of the same series rather than mixed into a steel system.

Order Eaton B-Line part 6A-12-HX24. The number reads out as 6 inch height, aluminum, 12 inch width, horizontal cross, 24 inch radius, which is how the rest of the Series 2-5 fitting range is coded too.
