Dynabrade 57851 Pad Base Non-vac Hook Face Urethane

Product Description

The DYNABRADE 57851 is a urethane pad base designed for non-vacuum disc sander applications with a hook-style attachment face. Constructed from medium-density urethane at 3/8 inch (10 mm) thickness, this pad base provides a consistent backing surface that supports proper disc contact and uniform abrasive action across the workpiece. It is engineered for use with reattachable hook-face discs, making disc changes fast and repeatable on the job. HVAC sheet metal fabricators, auto body technicians, and industrial maintenance trades are the most common installers of this component.

This pad base fits non-vacuum disc sander configurations where dust extraction through the pad is not required. The hook-face design allows compatible reattachable abrasive discs to seat firmly and release cleanly without adhesives. Medium-density urethane construction provides the compliance needed for finish sanding and blending work on flat and mildly contoured surfaces in both shop and field environments.

Key Features

• 3/8 inch (10 mm) urethane thickness for consistent disc backing
• Medium-density urethane construction balances conformability and support
• Hook-style attachment face accepts reattachable abrasive discs
• Non-vacuum design suits applications where dust extraction is handled separately
• Compatible with reattachable disc systems for fast, tool-free disc changes

Compatibility

Designed as an OEM-style replacement pad base for DYNABRADE non-vacuum disc sanders that use a hook-face disc attachment system.

Installation Notes

Installation of this pad base should be performed by a qualified technician with the tool disconnected from the air supply and at zero pressure before service begins. Ensure the mounting hardware is seated fully and the pad base is secure before attaching any abrasive disc. Inspect the hook face surface for wear or contamination that could reduce disc retention before returning the tool to service.
