Single 4 Inch Heavy Duty Polyurethane Swivel Wheel Caster
✔️ 4 Inch Red Polyurethane Wheel 600 Lb Load Steel Plate Mount

This single caster delivers steady roll for garage utility carts, medical gurneys, and custom shop rigs. The bright red tread stays clean while handling heavy industrial jobs. Workers appreciate how well it grips textured surfaces without transmitting harsh vibrations back to mounted instruments. Engineers favor this build because the thick polyurethane layer masks jagged seams and keeps rolling resistance low. It replaces worn-out plastic units in minutes using standard four-eighth inch bolts already bolted into most frame rails.

✅ Solid 4-inch diameter red polyurethane tread
✅ Rated for up to 600-pound dynamic load capacity
✅ Flat 4 by 4.5 inch drilled steel mounting base
✅ Non-conductive chemistry resists household solvents and oils
