Extreme Max 3005.3729 Heavy-Duty Plastic Roll-In Dock/Boat Lift Wheel

This heavy-duty plastic wheel makes roll-in docks and boat lifts easier to move. It is designed with 8-inch wide treads to move in rough, soft or uneven terrain and a robust 24-inch diameter. Plastic construction is perfect for constant submersion and exposure to harsh winter conditions without damage. The 1.98-inch diameter shaft will not rust or corrode, so the wheel will always move freely.
