The wheels of the transport castor set from Wagner are made of high-quality plastic. The housing is made of solid industrial steel, which has been galvanised to protect against corrosion. The design of the modern swivel chair double castor is attractive and functional. The hard tread of the wheels ensures excellent manoeuvrability on all soft/rugged floor surfaces. The castor is equipped with an 11 mm pin that fits into any swivel chair castor holder with a diameter of 11 mm. Simply insert - and roll.
