Astro Pneumatic Tool 4607 5" Hook and Loop Flexible Backing Plate 10x

The 4607 includes:

  • 10x Astro Pneumatic 4607 5" Hook and Loop Flexible Urethane Backing Plate


  • Use with your Porter-Cable 7424 or 7424XP polisher
  • Dual-action, flexible design minimizes heat transfer and forms itself to match the curves of your car
  • Features a molded hook and loop service for quick and easy pad changes
  • Unique properties of the molded urethan construction make this backing plate a true performer
  • Small enough to provide an adequate buffer zone between the edge of the foam pad and the molded urethan constructed backing plate

Whether it's for a 7424XP or 21mm Bigfoot polisher, DA or finisher sander, the 4607 is designed to be versatile enough to work on most all pad materials. Using a thicker J-Hook design made from a more heat resistant material, and implementing a new stronger adhesive, the hook & loop backing now lasts even longer in heavy use applications. By using a medium-hard density poly foam with a thin gradual tapered edge, the 4607 acts more like a soft pad on the edges for feathering work and tight curves, while lasting longer overall for the tough work.

WARNING: California's Proposition 65


When you open the plastic package, unscrew and discard the plastic cap that's located on the label side of the plate before use.
