Casters with urethane tread are used to reduce vibration and wear when rolling over hard tile or concrete. Urethane Casters: Hard surfaces like concrete and tile will wear down the wheels on standard casters. Braking Casters: These safety casters prevent chairs from rolling freely when unoccupied, then release to roll freely when weight is added. This safety feature has long been required on production seating sold in Europe. ESD Casters: BenchPro™ ESD chairs are equipped with double drag chains to dissipate static charges. ESD casters are only ordered by customers for their appearance, and when ordered, will replace the drag-chain. Note: These prices are to exchange standard casters for these optional casters or glides when purchasing chairs.
