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.
Same design as the Standard 03S Series but shorter and bigger so it can bear load capacity up to 300 kg. Enhanced PA wheel is strong and durable, it can rolls easy thanks to the double ball bearings. Suitable for lifting heavy machine.
