Chemical Guys BUFLC_BP_DA_3 Dual-Action Hook and Loop Molded Urethane Flexible Backing Plate (3.5 Inch), Yellow

The Dual-Action Hook and Loop Molded Urethane Flexible Backing Plate minimizes the heat transfer while it flexes just enough to contour to your vehicle's bends and curves. These backing plates are built tough and even carry a one year warranty. This flexible backing plate is ideal for use with Porter Cable 7424 Dual-Action Polisher or the Heavy Hitter Dual-Action Polisher. Urethane is flexible and very durable. Reinforced inner construction utilizes steel struts molded into the center hub to give the plate stability while maintaining a great even surface for pads. The backing plate is smaller than the pads to allow a generous lip of foam to protect the paint surface. Even if you turn the pad onto its side accidentally, there is an inch of soft, beveled urethane between the edge of the plate and the inner construction. The threaded post fits any polisher with a 5/16 inch diameter.
