Four Blocks in One
Each block has four flex settings
More Capability. Fewer Blocks.
Every Black Diamond sanding block adjusts through four distinct flex settings—from flexible for contours to rigid for large flat panels.
| What You Buy | Working Configurations |
|---|---|
| 24-inch Adjustable Block | 4 |
| 8" & 16" Set | 8 |
| Three-Block Bundle | 12 |
As you move across a panel, simply adjust the flexibility of the same block instead of stopping to switch tools—or wasting partially used sandpaper.
Why Adjustable Flexibility Matters
Traditional sanding systems require multiple blocks to cover different panel shapes. Black Diamond lets you adjust the same block in seconds.
| Traditional Fixed Blocks | Black Diamond Adjustable Blocks |
|---|---|
| One flex level per block | Four flex settings per block |
| Switch blocks as the panel changes | Adjust stiffness in seconds |
| Often replace or trim sandpaper when changing blocks | Keep using the same sandpaper on the same block |
| More blocks to purchase and organize | Fewer tools with greater versatility |
| Stop working to change tools | Stay focused and keep sanding |
Adjustable flexibility means fewer blocks, fewer interruptions, less wasted sandpaper, and a smoother workflow. Instead of changing tools as you move across a panel, simply adjust the same block and keep working.
