This part is the heel ledge that mounts to the back of the boot shell. Mounted using two screws and T nuts, the ledge allows the Silvretta heel land on a flat surface and clamp the boot down to the plate.
Includes stainless fasteners. CNC 'd, then hand tuned from engineered industrial acetal. PS: Takes close to a shop hour to make one of these!
