Enjoy the benefits of dust extraction and the firm flexibility of a foam sanding block with 3Mâ„¢ Hookitâ„¢ Dust Extraction Flexible Radius Sanding Blocks. Built for balance, these lightweight curved-face blocks deliver a flexible but firm backing for contour and bodyline restoration.
The built-in vacuum regulator lets the operator customize their perfect mix of dust-capture suction and freedom of movement.
The family of blocks includes three lengths: 5 1/4 inch (133 mm), 7 inch (178 mm), and 10 3/4 inch (273 mm) – plus a three-size block kit.
The 3Mâ„¢ Hookitâ„¢ attachment system means they’re compatible with 3Mâ„¢ Clean Sanding Sheets, 3Mâ„¢ Net Abrasive Sheets, and other hook-and-loop backed abrasive file sheets.
