This accessory is for use with the Guitar Style Strap when the Ukulele is equiped with 2 strap buttons. Another option: The Banjo Uke Straps can be converted to a Guitar Style Strap using 2 of these in combination with the 2 strap connectors availabe on that item. This solution is especially helpful if you would like quick removal of the strap from both ends. Works with the Leather or Polypro straps.
