Replaces standard 8 x 1 1/4 inner tubes. Makes the caster "Flat Free". Fits most brands of casters that use 8 x 1 1/4 tires and tubes. Reusable. Installs with minimal tools. Tire required.
Foam Insert Only
Poly Foam Insert arrived on time and was as advertised. It is being installed. It is of high quality. I would highly recommend this part.
