Norton 636425-06140 Psa Backup Pad 5 Inch 120 Grit

Product Description

The NORTON 636425-06140 is a 5-inch PSA (pressure-sensitive adhesive) medium tapered backup pad designed for use with dual-action and random orbital sanders. It accepts PSA-style abrasive discs and features five vacuum holes for dust extraction, keeping the work surface cleaner and extending disc life. The medium taper profile allows the pad to flex slightly at the edge, reducing the risk of swirl marks or gouging on contoured surfaces. This pad is sold individually and is suited for surface preparation, finishing, and blending tasks in automotive, woodworking, and general fabrication environments.

This backup pad is intended for trade and professional use with 5-inch dual-action and random orbital sanders equipped for PSA disc attachment. The five vacuum holes align with standard dust-port patterns to support connected or central vacuum dust collection. The Type X designation indicates the pad construction and flexibility rating. It is commonly used by body shop technicians, finish carpenters, and fabricators working on flat and mildly contoured panels at a 120 grit finishing stage.

Key Features

• 5-inch diameter PSA interface accepts pressure-sensitive adhesive abrasive discs
• Medium tapered profile reduces edge gouging on flat and contoured surfaces
• Five vacuum holes support dust extraction through the pad for cleaner work surfaces
• Type X construction rating for dual-action and random orbital sander compatibility

Compatibility

Designed as an OEM-style replacement backup pad for 5-inch dual-action and random orbital sanders that accept PSA abrasive discs with a five-hole vacuum port pattern.

Installation Notes

Installation and replacement of backup pads should be performed by a qualified technician familiar with pneumatic or electric orbital sander maintenance. Disconnect the sander from its air supply or electrical source before removing or attaching the backup pad. Ensure the threaded spindle connection is fully seated and secure before operation. Do not exceed the maximum RPM rating of the sander or the pad.
