• Our Center T system allows you to align the buff pad with the backing plate perfect every time. We have a permanently mounted plastic stud on the buffing pad. This stud fits snuggly in our 1975 backing plate. The plastic stud is mounted in our manufacturing process with ultimate precision to ensure a perfectly balanced buffing pad. On the market today you will see metal stud systems on backing plates or portable plastic tubes for centering your pads. The metal stud system can make contact with the painted surface and plastic tubes are easily lost. For these reasons we are confident in saying we make one of the most popular systems on the market today.
