4" YELLOWISH NYLON FIXED

Featuring a durable white polyolefin/nylon wheel, this 4″ fixed caster provides clean, reliable straight-line mobility for general-purpose utility equipment and storage racks. Its rigid design keeps carts tracking straight down aisles without requiring constant steering corrections from the operator.

The non-marking white wheel body resists wash-down chemicals, water absorption, and grease, making it suitable for sanitary and stockroom settings. It delivers high mechanical strength with minimal overall rolling resistance.
