This caster runs a Rubber wheel. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Rubber wheel performs best on rough, uneven, or outdoor surfaces such as asphalt, gravel, and cracked concrete. For non-marking or clean-environment needs, ask us about matching tread options.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
