Dual Action Backing Plate, 5″/6″ | High-Speed DA Polishers, Supporting Up To 10,000 OPM

The dual-action backing plate offers seamless contouring with high-speed polishers on car surfaces thanks to heat management and a balanced design for reducing heat and vibration, supporting high-speed DA polishers and 5-inch or 6-inch polishing pads. Crafted from durable polyurethane(PU) material, it allows great endurance to the heat and pressure. 

Perfect fit for high-speed DA polishers

The 5-inch or 6-inch DA backing plates are a perfect match for high-speed polishers with 5/16” diameter thread thanks to the quality material construction engineered for heat dissipation, pressure endurance, and balance, supporting up to 10,000 OPM DA polishers. Maxshine designed them for Maxshine M8S V1 and M8S V2; however, they are available to other high-speed polishers.  

The Smart design of the backing plate 

The backing plate is built with polyurethane, known for being heat and pressure-resistive, further helped by the 6-hole vents, allowing easy airflow to reduce heat. The center of the plate comprises the thread and six(6) reinforced steel struts, balancing the plate and resulting in less vibration for high-precision polishing. 

The hook and Loop fastener 

The backing plate provides a firm attachment with a pad for heavy tasks, staying centered and balanced.
