Review on RWM Casters 45 Series Plate Caster: Optimize Your Material Handling with Quality Products by Joel Young

These are large casters for very heavy applications, but unlike some heavy casters they rotate easily, making maneuvering a heavy load easier. And the price is amazing - about the same as many small and light skates. I have a set of skates that could be better with big narrow wheels that make them spin too easily. That's the only reason I didn't give them 5 stars.
