Thanks for that picture. I see how they fit now but don't understand how they anchor the puck or attach to anything that would keep the pucks from falling out. Just looks like they fit in the puck's hole and since the puck is a hard material, I don't think they cause them to expand. Can you clarify this for me? I notice that the puck's rubber ring is deteriorated like mine so the inserts must be doing their job.
