Ferrule

The TJ Pro Locking ferrule is the perfect fit for the TJ Aluminium Phosphate Pro hole cup. The notches on the ferrule allow the flagpin to lock into the holecup and prevent it from twisting once locked in place. It will also ensure that the flagpin sits completely upright in the cup and will not lean as can occur with some other ferrules on the market. Grooves on the ferrule prevent the flagpin from sticking in the cup. They also allow dirt and sand to pass through the cup leaving both the hole cup and ferrule clean. This is a metal ferrule that is available in both UK & US sizes.
