Solution to minimize overall height and maximize load capacity. Dual wheel casters also improve stability and swivel more easily than wider-face single wheels. However, this 40mm diameter caster is the most "ugly" one of the Series.

Smooth electroplated grant an elegant yet strong and durable experience. SUPO is proud to place its name on the caster, so you don't have to face typo brand like MESTER or MATTER anymore. Quality is also better than other China's ones. 6 months warranty.
