Non-marking phenolic caster wheels provide durable, low-maintenance mobility where strength, temperature tolerance, and reliability are essential. Made from compressed layers of resin-infused fibers, they roll easily on smooth, flat surfaces and can withstand chemical exposure. However, they do not resist moisture and should not be used in damp environments. This caster's swivel rig aids maneuverability through turns, and the top lock prevents rolling during loading, unloading, and other operations where stability is required.
