Theromplastic rubber (TPR) is an ideal tread choice for clean, noise-sensitive areas where floor protection and quiet operation are critical. The cushioned grip of the rubber surface provides a smooth ride, even over small obstacles. TPR is a durable, non-conductive material that resists chemicals, steam, salts, and oils. 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.
