3M 7000045510 Hookit Sanding Block Kit 7-piece

Product Description

The 3M 7000045510 is a seven-piece foam sanding block kit designed for use with Hookit loop-attachment abrasive products. Each block in the kit provides a rigid, conformable backing that maintains consistent surface contact during sanding operations. The kit covers the seven most commonly used block profiles, making it a practical shop accessory for technicians who work with body filler, primer, and other substrate materials. At 1.85 pounds, the full kit ships as a single unit and is well-suited for both mobile service setups and fixed shop environments.

This kit is used in automotive body and paint applications where controlled, flat or contoured sanding is required. Foam blocks deliver even pressure distribution across the abrasive sheet, reducing the risk of high spots when leveling filler or primer coats. The Hookit attachment system allows abrasive sheets to be swapped quickly without adhesive, keeping workflow moving during production or repair work. Body technicians and painters working in collision repair or refinishing will find this assortment covers the range of block shapes needed across typical job stages.
