This holder solves the problem of clamping a KIK cylinder in a vise without the vise seizing up the tailpiece, which needs to remain free to rotate. Put your KIK cylinder inside the holder, clamp the whole thing in your vise, and pick your KIK lock hassle-free.
A cutout at the back accommodates a wide variety of lock tailpieces. This is one of the best KIK holder designs out there.
