Our indoor replacement casters are readily available in 3 configurations and 2 sizes: Fixed, Swivel, and Swivel with brakes, 6″ or 8″.
This caster is ideal for carts that will be use for your indoor show. The wheel is made of non-marring thermo-plastic rubber (TPR) and has no tread pattern that could potentially pick up gravel and damage a gym floor or tarp. You may want to retrofit some of your existing carts specifically for your indoor show, depending on the rules of your local competition circuit.
