Quiet dolly is precision-engineered for quiet operation. Nonmarking red casters easily identify this quiet dolly from traditional dollies. Special design eliminates 88 percent of traditional dolly noise across both smooth and uneven surfaces. All-plastic construction resists rust, chipping and denting. Easy twist-on/twist-off dolly provides safe mobility and handling of heavy loads. Heavy-duty wheels with swivel capabilities provide for easy mobility. Dolly features a 350 lb. maximum load capacity and fits Rubbermaid 2620, 2632, 2643 and 2655 (sold separately).
