Grip collar avoids what results from the left grip moving inward over time: "Grip Sawing" or "Grip Sliding" (pictured below) is what happens. Grip collar stops that.

The collar has 3mm nuts encapsulated and uses machine screws for fastening. The hardware is included and is made of stainless steel.
