This is a quick and small tool to help you readjust the Wolfcraft 4650 doweling jig rule to previously drilled holes, in case the shelf you are working on is longer than the rule itself.
Click one or two of these blocks into the jig's first holes, insert a dowel or shelf peg into the holes you just drilled and align those dowels/ pegs to the blocks.
No additional hardware is required, the design is consistent with and based on the flexibility of the material.
