Swivel Caster with Side Lock - 6" x 2" Polypropylene Wheel, 600 lb. Cap.

Polypropylene caster wheels are the most cost-effective option for mobility on hard, smooth surfaces. Durable injection molded plastic resists moisture and chemicals, offers low rolling resistance, and won't mark floors. Polypropylene wheels can be noisy as they roll, so they're best suited for environments that don't require quiet operation. This caster's swivel rig aids maneuverability through turns, and the side lock prevents rolling during loading, unloading, and other operations where stability is required.
