Many computer manufacturers and electronics companies require conductive wheels on assembly carts to eliminate static build-up and discharge. Although conductive caster wheels have existed for years, almost all of them mark floors. Colson has solved this problem with our selection of Performa Conductive Wheels. These models combine a soft cushion ride with a nonmarking tread design. All wheels feature a cushion grey Performa tread bonded to a black Polyolefin wheel core.
