A ring sits over the top of a shaft and holds the flight slot together, which is where polycarbonate and nylon shafts take the most stress.

Rings cost a fraction of the shafts they save, which is unusual for a darts accessory. Fitting one to each shaft extends the life of all of them, and the flight sits more securely into the bargain.

Titanium holds its shape and its grip indefinitely; anodised aluminium is the mid option and keeps its colour rather than dulling. Spring rings do a related job at the flight end, locking the flight in place rather than relying on friction alone.
