Description
Siafast Hook and Loop Backup Pad is a Siafast backup pad for 5 inch no-hole abrasive discs on random orbital sanding tools. The 4580.8409.0000 pad has a 5/16-24 thread, 1/2 inch medium edge construction, and hook and loop face for fast abrasive changes.
Siafast backup pad Benefits
- Hook and loop face lets operators change abrasive discs quickly during multi-step sanding.
- 5 inch no-hole format fits non-vacuum sanding jobs and compatible Siafast discs.
- 5/16-24 thread matches many common random orbital sander spindles.
- 1/2 inch medium edge gives a balance of support and compliance for flat and lightly shaped surfaces.
- Dedicated backup pad keeps the abrasive centered and supported during finish work.
Use this pad when a sanding station runs Siafast discs and needs a clean attachment surface. A worn backup pad can reduce disc grip, cause chatter, or let the abrasive lift at the edge. Replace the pad when the hooks no longer hold the disc evenly or when the foam edge becomes damaged.
