4" Stainless Steel Caster with Performa Rubber (Flat/Conductive) Wheel - D4.04109.455 COND SS

About This Caster - D4.04109.455 COND SS

Choose this 4-inch Defender D4 swivel when a steering cart has to drain static charge in an ESD-sensitive or flammable workspace.

The swivel guides the front of the cart through tight bays, with a 3.375-inch swivel radius to allow, while the conductive flat-tread Performa wheel carries static from the cart down through the caster to ground rather than letting it build up, which protects electronics and reduces spark risk near 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 finished surface. The stainless steel frame suits wash-down service, and the pedestal precision ball bearing keeps wheel and swivel turning smoothly. Soft rubber keeps the load class modest, so static control comes first. It serves from -45 to 180°F.

Ideal applications

• ESD-sensitive carts that must drain static while steering
• Flammable or solvent bays where maneuverable spark control is needed
• Quiet stable-footprint front corners under modest loads

Verify the conductive resistance spec and that the wheel and swivel both carry the path to ground, plus the 3.375-inch swivel radius, before ordering.

Pairs with: matching conductive Defender D4 casters on all four corners so the whole cart stays grounded, including the rigid conductive 49MC42GT-02.

Wrong fit? No static concern, just a quiet non-marking swivel? See the grey flat-tread swivel 49MG42V-02 in the Colson collection.
