These 3M™ Hookit™ blocks combine the lightweight flexibility of traditional foam blocks with the dust extraction power and control of rigid dust-free sanding blocks. They feature a convex face which can help you easily restore contours and bodylines, while still providing a firm backing for abrasives. They include a vacuum regulator that lets the operator adjust suction for easier block control when sanding.

• A lightweight curved-face sanding block with a firm-but-flexible backing which helps easily restore contours and bodylines.
• When used with a vacuum system and compatible abrasives, this 3M™ Hookit™ Dust Extraction Flexible Radius Sanding Block helps capture dust which can increase abrasive life while helping reduce dust in the shop environment.
• The 3M™ Hookit™ hook and loop attachment system allows for easy abrasive changeouts.
• The built-in vacuum control allows the operator to adjust suction to prevent the block from sticking to the substrate while maximizing dust capture.
• 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.
