Our Never-Flat Series Caster provides similar cushion and easy-rolling just like traditional air-filled casters but without the problem of going flat. The soft rubber inner-tube gives plenty of support to the belted outer tire. Never Flat Casters are made of micro-cellular polyurethane material with zinc-plated steel brackets and mounting plates. A 5/8in. ball bearing bore gives you smooth operation when transporting or moving objects. These casters are perfect for indoor or outdoor uses, and you'll never need to "air up" your tires again.
