This part can be screwed in the small square holes of 7-league boots (7 Meilen Stiefel) with a single M5 screw (hexagon head).
With it you are able to mount a lightmod, a bottleholder or something else onto your Stilts.
I suggest buying two of them per stilt in the sturdy white or dyed Strong & Flexible material.
