8"X2" Stainless Steel Top Plate Rigid Caster with Performa Rubber (Flat/Conductive) Wheel - D4.08108.455 COND SS

About This Caster - D4.08108.455 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 flat-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. The flat profile gives a stable footprint and the soft rubber rolls quietly and stays easy on floors, though the conductive compound can mark a light surface. At 8 inches it is the tallest wheel in the line, bridging the widest cracks and clearing 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 spark control and big clearance
• Quiet stable-footprint rear corners that track straight

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 flat-tread rigid D4.08108.455 in the Colson collection.
