Protect the Life of Your Disc Pad To protect the integrity and life of your 3M™ Hookit™ Pad, the 3M™ Hookit™ Clean Sanding Hook Saver was devised. With holes that exactly match the multi-hole design of your Clean Sanding disc pad, it extends the life of your pad and maintains the integrity of the clean sanding system, making sure you get the most return from your investment. 3M™ Hookit™ systems permits thousands of easy attachments, detachments and reattachments. Stiff hooks on the receiving side mesh with pliable loops on the disc to provide secure abrasive attachment. Over time, repeated disc changes will fatigue the hooks on the disc pad and reduce the level of attachment force between the disc and pad. To protect your specialized Hookit™ Pad and extend its useful life, 3M™ has developed this low-cost hook saver attachment. Maximize Performance and Productivity Part of the entire 3M™ Clean Sanding System, the Clean Sanding Hook Saver is just one small part of the big picture: an integrated system of tools and accessories engineered to work in concert to help you achieve the best results possible and most effectively, while producing a cleaner work environment for both worker health and productivity.
