We carry collared ferrules for the Ping Glide wedges. The part number is PGC003. On the Vokey, they don’t have the same kind of collared ferrule as the Ping. You can most likely use the same ferrules as we have listed for the AP! and AP2 irons, which is the BB9063. this is an aftermarket ferrule designed for Titleist irons (.355″). You don’t have to use the collared type ferule on the Vokey. You could use a standard non collared ferrule. I am not sure what the OD of the hosel is so I’m not sure exactly the one that will work, but most likely one like our 66TI. Below is a link to our ferrule category page. On each page we list the specs, including the OD, so if you can measure the OD of the hosel then you can know which ferrule will be big enough.
