Pack of 12 Black .370" Iron Ferrules.
Length .500", OD .540", ID .370".
All ferrules have a 19° countersink which allows a cushion of epoxy to form between the top of the hosel and the inside of the ferrule, strengthening the bond. Each ferrule also is “pre-washed,” arriving at your shop with a high-gloss finish and no need for an acetone wipe to make it shine!
