A Back-up Pad for Faster, Easier, Better Sanding
Designed for use with 3M™ Hookit™ abrasive discs, our 3M™ Hookit™ Back-up Pad is built for added support, control and speed during automotive sanding jobs from paint removal to polishing. These 6” and 7” pads are available with soft, medium and hard density foam for a range of applications from paint stripping to polishing. Each center-hole pad features a flat, rigid center for support and softer, tapered edges for added control. Seven-hole or 15-hole patterns are built in to improve dust extraction, reduce loading and increase abrasive life. Disc pads are available with 5/8-11 interior threads to fit a variety of low-speed (maximum 3000 RPM) power polishing and sanding tools.
About Our Hookit™ Attachment System for Faster Change-Outs
The Hookit™ attachment system has a hook-and-loop feature which makes disc attachment, removal, and re-attachment clean and easy. It also facilitates use and re-use of the disc for maximum product life. Hookit™ sheets have a brushed nylon loop backing of the type most commonly used in everyday hook-and-loop applications. A range of Hookit™ disc backup pads features hooks which grip the brushed nylon loop backing. It’s simple: just attach the disc and start sanding. The disc removes just as cleanly and easily. The Hookit™ system is designed for work spaces and applications where adhesive backed abrasives may become contaminated by dust, dirt or debris.
