8" x 4" Rigid Plate Caster with Dual Ergo Wheel
Our Dual-Ergo wheels were designed to replace tradional single wheels for better maneuvering while not widening the footprint and swivel radius. These dual wheels alone have shown a minimum 35-50% push/pull force reduction. As well as proven to reduce rolling resistance and helps with the swiveling action. Each wheel has 2 independent rolling wheels and are maintenance free for the life of the wheel. They feature large sealed precision ball bearings and a non-marking tread.
Great for manufacturing plants, tow lines and where stringent push/pull forces are required. Commonly used at airline manufacturers for working platforms next to the airplane on the assembly line.
