How the Adapter Ring Works
The Jaw Muzzle adapter ring uses the principal of the three-jaw chuck to adapt to any round bearing housing. The three tabs are clamped to the bearing housing with a hose clamp. The Jaw Muzzle adapter ring is centered on and attached to the bearing housing of the grinder by a hose clamp. Click on installation instructions for a schematic view of the adapter ring.
