Suitable for all applications when material or packages need to be transferred, sorted or turned in any direction. Roller design is based on the use of four free-turning barrel shaped rollers mounted in a 90° staggered pattern around the perimeter of a main core wheel, thus allowing for a multi-directional roller function. Rollers are available in three diameters mounted on either five or ten foot U-shaped rails. Rollers are made of corrosion resistant polyacetal with stainless steel axles. U-shaped rails are made of 14 gauge galvanized steel. Each five foot section has 15 rollers. Each ten foot section has 30 rollers. All have internal diameter of .330 inch.
