They are best for facilities and users who need a robust upgrade over stock casters and want non-marking wheels that protect floors.

Who It's For

This set is aimed at maintenance staff, workshop owners, and facilities managers who need a dependable replacement for original Rubbermaid cart casters or want an upgrade that increases weight capacity and reduces floor marking.
