Using the BORA Parallel Clamp Blocks is easy. First, find a standard parallel clamp and slide it into the block through the channels. For better support, especially when using longer clamps, you can connect multiple blocks together. This will stop the clamps from tipping over. When working on projects like making frames or boxes, these blocks will help you align your clamps quickly and accurately. As for storage, use the two countersunk screw holes to mount the blocks on a workbench or wall. Keep the blocks in a dry place to prevent the plastic from getting damaged. If they get dirty, just wipe them with a clean, dry cloth. Avoid using sharp objects on the blocks as it may scratch the surface and affect their performance.
