Premiers plastic dock wheels are designed for roll-in docks and boat lifts. Because they are made of heavy duty plastic, they will never wear out; wont rust on the shaft; roll easily on all terrains; will handle even the heaviest docks; and require no maintenance. Optional water inlets and drains are available. Reduce your labor and time costs, and forget those trips to the salvage yard for rims and tires; and problems matching tires to your rims. Premier Dock Wheels are the strongest in the industry, see the 3rd Party Test Results Chart.
