This caster includes a durable yet economical glass-filled nylon wheel that resists water, chemicals, and impacts, and rolls easily over smooth surfaces, even at high loads. The wheel is non-marking, and its low profile makes it a popular choice for server racks and cabinets. 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.
