Vestil CST-F-CR Series casters feature premium thermoplastic rubber (TPR) construction that offers resistance to solvents, grease, oils and water. These units are chemically bonded to the polyolefin wheel core, thereby ensuring exceptional floor preservation against electrostatic discharge and are ideal for areas which are highly sensitive to static buildups, such as electronic companies, manufacturing plants and medical engineering facilities. They are further integrated with ball bearings for a mark-free, smooth and quiet rolling operation. Choose for an extensive range of these rubber (DK- conductive) casters, available in sizes ranging from 4 x 2 sq. in. to 8 x 2 sq. in. on Raptor Supplies.
