The Rupes Back Up Pad has a BigFoot system which offers the lowest vibration levels in the industry. This is due to the precisely balanced relationship between the motor's counterbalance system and the accessory items during the polishing process. As the microfiber polishing pads are heavier than the normal foam polishing pads, Rupes has designed a special backing plate for use with the microfiber pads. The new backing plate is lighter and has a re-positioned centre of gravity to assure the perfect balance of BigFoot with the new microfiber pads. The ventilation characteristics of the new backing pad combined with the slots in the microfiber polishing pads effectively dissipate heat and maintain the work surface temperature at an acceptable level.
