The wheel has a unique locking system that is very beautiful and the operating force is significantly lighter than similar products.

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.
