All the existing tool-check holders seem to be based around peg boards, or gridfinity or similar. This holder is designed to bolt/screw to a wall or similar using a pair of 4mm bolts/screws. Holds the Wera Tool-Check Modular 1 snuggly for easy access. Depending on what surface you attach it to, the flap over the bits can still be opened to access the bits without taking the tool-check out of the holder.
