These high-strength polycarbonate sanding blocks are designed for superior autobody finishing, featuring a patented "vertebrate" design that offers hard, uniform pressure with excellent flexibility for contouring.

Each block is CNC machined and routered leaving no sharp edges.

All blocks feature a Limited Lifetime Warranty.

• Vertebrate Design for Even Pressure: The unique structure distributes pressure evenly across the entire surface, preventing high and low spots, unlike softer foam blocks.
• Optimal Flexibility Options: Available in Rigid (for flat panels/initial filler cut), Flex (for gentle curves), and Ultra-Flex (for tighter curves) to match specific sanding needs.
• Durable Polycarbonate Construction: Made from rigid, durable polycarbonate, these blocks are designed to hold their shape, resist twisting, and last.
• Ergonomic Design: Comfortable handle and no sharp edges, make them easy to handle during long sanding sessions.
• Versatility: Compatible with both sticky-back and hook-and-loop sandpaper.
• Superior Flattening Capabilities: These tools are excellent for achieving a mirror-like finish by efficiently cutting through orange peel and surface.
