Each NeoTeq series caster uses a non-marking neoprene wheel to provide easy turning and maneuverability. The dual ball swivel raceway adds strength, while the precision ball bearings in the wheel increases roll-ability. Bright chrome provides an attractive, chemical-resistant finish. Matching chrome thread guards are standard on all models to reduce debris entanglement. A durable, coated metal dust shield helps prevent dirt and dust build-up in the swivel raceway.
