Medium Duty Phenolic Casters with Total Lock are primarily designed for applications involving material handling carts, food processing equipment, and various institutional uses. They are impressively resistant to oil, grease, and solvents, making them ideal for challenging environments. Thanks to their non-metallic and non-sparking nature, they also contribute significantly to safety. With their hard tread, these casters roll with ease, making them quieter than steel wheels. The unique construction of these casters, featuring phenolic resin mixed with macerated canvas, results in a high-capacity, high-impact-resistant wheel. The Caster Guy carries many medium duty casters like these with capacity up to 1,250lbs that also include the popular total lock mechanism.
