8 in Colson 4 Series Swivel Top Plate Roller Bearing Caster w/ Round Performa Rubber Wheels

Performa wheels offer the advantages of both hard and soft tread materials in a single wheel. Like a hard treadwheel, Performa rolls easily and is very durable. Like a soft tread wheel, it rolls quietly, protects floors and resists impacts with a cushioned ride. It also features maximum weather-ability, low-temperature flexibility, resistance to chemicals, water and steam, and rejects floor debris such as metal shavings. Non-marking thermoplastic elastomer tread is permanently bonded to a ribbed polyolefin wheel core.
