Extra-soft performance rubber (TPE) caster wheels offer the ultimate in smooth, quiet mobility. Longer wearing than TPR and rubber-on-iron, the grippy tread also delivers ergonomic advantages with easy rolling and superior shock absorption. TPE resists chemicals and moisture, and it rejects debris— even metal shavings. 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.
