R Swage Ladder is a structure consisting of two side rails, connected by individual rungs and is manufactured in accordance with NEMA Standard VE-1. Atkore rungs are fastened to the side members by an exclusive swaging process. This assembly method ensures a superior mechanical and electrical connection. 2R

Rung Spacing - The interval at which rungs are swaged to the side member is measured from centerline of rung to centerline of rung. Atkore manufactures straight lengths with three standard run spacings: 6", 9", and 12". 18" rung spacing is available upon request on widths 24" or smaller. Rung spacing is generally determined by size and type of cable being supported. When in doubt, 9" rung spacing is a typically accepted compromise. Length - The longitudinal dimensions of standard Atkore Cable Ladder are 10', 12', 20', and 24'. Custom lengths may be available upon request.
Side Members - Atkore side members are designed with top and bottom flanges turned outward. This simplifies fastening the cable tray to the supports. Cable tray with outward facing flanges allows complete access within the cable loading area and eliminates the possibility of cable damage from sharp edges within the cable area. The return on the top flange strengthens the side member and allows cable to be smoothly dropped over the side. Rung - Atkore ladder rungs are 1.00" diameter tubing flattened on top to provide a cable bearing surface. This construction allows cable to drop out anywhere without contacting a sharp edge.
