This lot includes 8 of the 4x1 1/4" Colson hi tech performe non marking rubber (flat) swivel casters, 2 of the 4x 1 1/4" phenolic (flat) swivel casters, one non marking rubber wheel, and 6 of the phenolic wheels. They came out of old inventory and have some cosmetic issues. All rotate as they should, and all have had 3 in 1 oil added for storage. I'm willing to take offers on price and quantity.
