Review on RWM Casters Urethane Polypropylene Capacity Material Handling Products for Casters by Chris Owens

Place six of these under a 900 pound drafting table. The weight is carried without problems. The larger wheels make this 8 x 4 x 3.5 foot beast so easy to move that I actually rolled it across the room and crashed into another table just by leaning on it before hitting the brakes. There are no marks on the linoleum. Excess? Yes. Its worth it? Fully. PS Don't waste your time with junk at Home Depot or Lowes. I bought them for $16 each with free shipping. The ones in stores are $8 each with a maximum load of 200 pounds, and they all come in different sizes. Turn? Pan with brake? Check the specs online. They differ by 0.2 inches.
