Comes with Champagne Rings.
1) The wide opening makes flights very easy to insert.
2) The built-in flight guards prevent the flight from tearing from the bottom-up.
3) The Champagne Ring or Shell Lock ring causes the tines to compress, creating a strong hold and protecting the shaft.
L-SHaft is only compatible with Shell Lock Rings and Champagne Rings
