8"X2" Stainless Steel Top Plate Rigid Caster with Performa Rubber (Round/Conductive) Wheel - D4.08108.555 COND SS

About This Caster - D4.08108.555 COND SS

Choose this 8-inch Defender D4 rigid when a cart must drain static in an ESD-sensitive or flammable area and ride over the roughest floors.

The conductive round-tread Performa wheel carries static charge from the cart through the caster to ground rather than letting it build up, protecting electronics and reducing spark risk around solvents or dust. Its round profile keeps rolling resistance low and the soft rubber rolls quietly, though the conductive compound can mark a light surface. The tallest 8-inch wheel bridges the widest cracks and clears the biggest obstacles, and the pedestal precision ball bearing keeps it rolling smoothly, on a stainless steel frame for corrosion. Rigid means it tracks straight at the rear. It serves from -45 to 180°F.

Ideal applications

• Tall 8-inch ESD-sensitive carts that drain static on rough floors
• Flammable or solvent areas needing low-resistance static control
• Round-tread rear corners that clear the biggest obstacles

Verify the conductive resistance spec and that the full caster path to ground is conductive, plus the 9-1/2-inch mount height, before ordering.

Pairs with: matching conductive Defender D4 casters on all four corners so the whole cart stays grounded, from the Colson collection.

Wrong fit? No static concern, just a quiet non-marking wheel? See the 8-inch grey round-tread precision-ball rigid D4.08108.555 in the Colson collection.
