Mirka 106 6" Vinyl Faced PSA Backup Pad Medium Density 5/16-24

The Mirka 106 is a professional-grade 6-inch backup pad designed for use with PSA (pressure-sensitive adhesive) sanding discs on dual-action sanders. This medium-density pad features a specially treated vinyl face that provides superior adhesion for PSA-backed sanding discs while allowing clean removal without paper delamination or tearing.

Key Features:

• 6-inch diameter vinyl-faced backup pad with PSA attachment system
• Medium density molded polymer construction for durability and consistent performance
• 5/16 x 24 threaded spindle connection fits most standard DA sanders
• No-hole configuration ideal for applications where dust collection is not required
• Precision-balanced design eliminates vibration for smooth operation
• Specially treated vinyl face ensures excellent disc adhesion and clean removal

This backup pad is engineered for professional automotive refinishing, woodworking, and industrial sanding applications where PSA disc attachment is preferred. The balanced construction reduces operator fatigue and delivers consistent results across the entire sanding surface.
