The Johnson Abrasives Foam Backup Pad (MPN 33961) provides a durable, hook-and-loop interface for 9″ sanding discs and is optimized for use with Porter-Cable drywall sanders. Its resilient foam construction supports multiple disc changes with minimal wear, reducing downtime and replacement costs. Compatible with standard 9″ hook-and-loop discs, this pad simplifies disc swaps and delivers consistent sanding performance across drywall and other flat surfaces.

Key Features and Benefits

  • Hook-and-Loop Attachment: Secures abrasive discs firmly while allowing rapid disc changes, saving time on the job site.
  • Durable Foam Core: Withstands repeated disc replacements, lasting through multiple sanding cycles and cutting long-term replacement expenses.
  • Porter-Cable Compatibility: Direct fit for Porter-Cable 7800 and Radius 360 drywall sanders, plus any 9″ disc sander using the standard nut mounting system.
  • Improved Disc Life: Using hook-and-loop discs with this pad extends abrasive life compared to glued-on pads, offering more sanding per disc.
  • Cost Efficiency: Reduces the need for frequent pad replacements and cuts abrasive costs by leveraging reusable hook-and-loop sanding discs.

Install the foam backup pad by removing the stock nut on your Porter-Cable sander, slipping the pad over the arbor, and reattaching the nut. Use only hook-and-loop sanding discs designed for 9″ pads. To maximize pad life, clean the foam surface periodically to remove dust buildup and store the sander face-down on a clean surface when not in use.
