Solid Conversion Discs (PSA to H&L) – Restore Your Backup Pad

These Solid Conversion Discs are designed to convert your existing PSA (Pressure Sensitive Adhesive) backup pad into a Hook & Loop (H&L) system, giving you the flexibility of quick disc changes without replacing your entire pad.

Over time, the heat and friction from sanding can wear down the nylon hooks on your backup pad, causing discs to lose grip and detach during use. Instead of purchasing a costly new pad, simply apply one of these conversion discs to restore the hook surface and extend the life of your equipment.


How It Works

  • Peel-and-stick PSA backing securely bonds to your existing backup pad
  • The H&L (Hook & Loop) surface allows you to attach standard hook & loop sanding discs
  • Instantly converts worn or PSA-only pads into reusable H&L systems

Key Features

  • Cost-Effective Solution: Restore instead of replacing expensive backup pads
  • Strong Adhesion: PSA backing ensures a secure, long-lasting bond
  • Durable Hook Surface: Designed to withstand sanding heat and friction
  • Quick Conversion: Upgrade your pad in minutes
  • Versatile Use: Compatible with most standard sanding applications

Sizing Guide (Discs are slightly undersized for proper fit)

  • 1-3/8" → fits 1-1/2" pad
  • 1-7/8" → fits 2" pad
  • 2-3/4" → fits 3" pad

Applications

  • Metalworking and fabrication
  • Automotive and body work

Grace ★★★★★

Finally, a way to get more life out of my old backup pad. The disc locked onto the PSA pad perfectly and the hook and loop surface holds my sandpaper firmly.

Robert ★★★★★

These discs fit perfectly on my old sander and the hook and loop side grips pads way better than the original PSA surface did. Finally got my backup pad working like new for about a third of the cost of replacing the whole thing.

Emma ★★★★★

I was worried about compatibility, but these conversion discs fit perfectly on my old PSA pad, and the hook-and-loop surface grabs sandpaper sheets securely without slipping during use. Definitely saved me from having to buy a whole new backup pad.
