Grips on racquets are attached near the throat with electrical tape. On top of that there is a rubber outer ring (about a 1/2" wide) that hides the electrical tape. What is it the rubber ring called? Have a link to any at TW? I want to purchase a few from TW (Prince if they have them) but can't unless I know what they are. I have some loose ones and it's a bit annoying so figure I could buy some new (hopefully tighter) ones to ease my mind.
