4" x 1-1/4" Thermoplastic Rubber (TPR) Wheel - Part # QMIR4G3-T

Thermoplastic rubber caster wheels deliver smooth, quiet performance with the durability of a hard tread and the floor protection of a soft tread. They’re non-marking, chemical-resistant, and reject debris—perfect for environments requiring clean, cushioned, and quiet mobility.

*We would not recommend this wheel for applications that require sitting in one spot for long periods of time under load as it can lead to flat spotting.
