B-Line Eaton series imperial cable tray and ladder, 6" Height, 66.0625" Length, 30" Width, Series 2-5 horizontal bend, Aluminum, 90° Angle, 48" Radius

Allow for a 48 inch centerline radius and an overall part length of 66-1/16 inches through the turn. On a 90 degree bend that means the run leaves the corner square, so you need clear space in both directions beyond the point where your straight sections stop. Tight ceiling corners and close wall returns are where this one gets rejected on site.

Radius is a cable bend radius decision, not just a fitting choice. Large diameter power feeders and fiber have minimum bending radii, and a 48 inch radius turn lets those cables round the corner without being forced past their limit. If the cables in the run are small and flexible, a shorter radius bend takes up far less corridor space; if you are pulling heavy MV feeders or fiber trunks, the 48 inch radius is the one that keeps the pull legal and the jackets intact.

Aluminum. That is the usual pick for corrosive, damp, or coastal areas and for weight sensitive overhead runs, since it will not rust the way painted steel does once the coating is scratched. Aluminum tray and fittings should be kept in the same material family through the run, so pair it with aluminum straight sections rather than mixing in steel at a splice.

A horizontal bend turns the run left or right while staying level, which is what you want going around a corridor corner or a column. If the run has to change elevation, that is a vertical inside or outside bend instead. If a second branch needs to leave the main run while the main run continues, you want a tee or cross, not a 90 degree bend.

Order Eaton B-Line model 6A-30-90HB48. The number reads across as 6 inch depth, 30 inch width, 90 degree horizontal bend, 48 inch radius, in aluminum.

31.5 lb. A 30 inch wide fitting at that weight is a two-man lift into hangers in practice, mostly because of its 66-1/16 inch span and awkward shape rather than the load. Factor it into your trapeze spacing at the corner, since bends usually want support on both legs close to the splice plates.

The 6A-30-90HB48 bend is CE marked. That is the only marking stated for the part, so if your spec calls out a particular tray listing beyond CE, confirm against the Eaton B-Line series data for the run you are building.
