NeoTeq Dual series casters have non-marking neoprene wheels that provide easy turning and maneuverability. Dual ball swivel raceway adds strength, and precision ball bearings in the wheels increase roll-ability. Bright chrome provides an attractive, chemical-resistant finish. Matching chrome thread guards are standard on all models to reduce debris entanglement. An upper dustcap helps prevent dirt and dust build-up in the swivel raceway.
