Thermoplastic Rubber wheels offer the advantages of both hard and soft tread materials in a single wheel. Like a hard tread wheel, they roll easily and is very durable. Like a soft tread wheel, it rolls quietly, protects floors and resists impacts with a cushion ride. It also features maximum weatherability, 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 ribbed polyolefin wheel core. Available in 3, 4, 5, 6, 8in+ sizes. Don’t see a size you like? Call us!
