DynaGrip "O" Rings are designed to fit in the groove in your dart barrel, to provide a non-slip surface .
DynaGrip "O" Rings come in two diameters and a variety of colors to match your color preference. Use just one color or mix and match to create the feel and look you desire. One package contains 18 pieces. Choose Your size, small or large.
These O-rings will not function as a lock ring for your points or shafts........they are too large for that application. DynaGrips are sized to fit in the grooves on the outside of your dart barrel.
