Tacit USA Holecups fit USA size ferrules. Available in Nylon or Aluminum to match your choice of ferrule. The Tacit Holecup & Ferrule combination has been an ever present on the top courses for 30 years now. The unique profile and splines of the ferrule and Holecup combined ensure the flagstick does not lean, twist or rotate which would usually cause excessive wear or blowouts. The aluminum cup has the added benefit of being able to add an interchangeable wrap which can be branded with corporate or event logs.
