This leather adapter lets you connect the two shoulder straps on our "Harness Strap" together so you have a single connection point to the strap button on the guitar. It works on our 2" and 3" double shoulder guitar strap models. The adapter also allows you to keep the shoulder straps connected so you can simply lift the loop that's created over your head when putting on or taking off the guitar strap.
Please note: this item is not needed for our Leather Harness Straps. They have a built in connector.
