Duralast Wheels for Industrial and Commercial Use

Resilience & Durability | 1,000 – 9,000 lbs. Capacity

Engineered for Optimal Performance

Duralast Wheels are liquid cast to approximately 1/2" thickness and chemically bonded onto iron wheel centers. The green tread is chemically inert, non-sparking, and non-conductive, ensuring maximum strength and safety in various environments.

Ideal for Heavy-Duty Applications

Perfect for applications requiring a capacity range of 1,000 – 9,000 lbs. Resistant to ozone, grease, most oils, and solvents, these wheels ensure optimal functionality in industrial and commercial settings while being non-marking to floors.

Unmatched Performance & Safety

Equip your space with Duralast Wheels designed to wear like steel, ensuring safety, and efficiency. Guaranteed against tread separation for one year in ordinary free-wheeling applications, experience the pinnacle of wheel technology and innovation.
