About This Caster - D4.05108.459 COND SS WB29
Reach for this 5-inch Defender D4 rigid when a heavier cart must drain static in an ESD-sensitive or flammable area, pushed slowly.
The roller bearing carries the most weight of the three bearings at a slow pace, and the conductive flat-tread Performa wheel carries static charge from the cart through the caster to ground, 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 5 inches it clears thresholds more easily than a smaller wheel, on a stainless steel frame for corrosive bays. Rigid means it tracks straight at the rear. It serves from -45 to 180°F.
Ideal applications
- Heavier 5-inch ESD-sensitive carts that must drain static slowly
- Flammable or solvent areas needing static control under load
- Quiet stable-footprint rear corners under slower heavy loads
Verify the conductive resistance spec and full path to ground, confirm the soft-rubber roller load class, and check the 6-1/2-inch mount height before ordering.
Pairs with: matching conductive Defender D4 casters on all four corners so the loaded cart stays grounded, from the Colson collection.
Wrong fit? No static concern, just a quiet non-marking wheel? See the 5-inch grey flat-tread roller rigid D4.05108.459 in the Colson collection.
Also in this family: the 5-inch conductive flat-tread precision-ball rigid D4.05108.455 COND, or the full Colson collection.
