The big difference between the Standard and Heavy Duty Auto Dolly is in the caster type and size. Heavy Duty Auto Dolly Casters are larger in diameter and outfitted with three beefy sets of bearings: One on the swivel and two on the axle. All of this adds up to three advantages over standard casters:

• It takes less force to get things moving and keep them moving.
• The larger diameter wheels also handle expansion joints better than the smaller ones.
• Greater weight capacities than standard Auto Dolly sets: 10,000 lbs vs 6,000 lbs.

The Heavy Duty casters share the Standard casters' same non-marring polyolefin material that won't mark-up or peel your floor like steel wheels will.

This kit contains 8 heavy duty casters that are 2 1/2" in diameter and have bearings on both the swivel and the axle. Upgrade current standard duty casters up to 5,000 lbs per pair.
