The Auto Lock Swivel Strap is the perfect solution for strap buttons on the back of the guitar body. Combining two D’Addario innovations, the Auto Lock Swivel supports up to 162 lbs. and allows you to lock onto the strap button with the patented Auto Lock end design, while the swivel prevents the strap from unwanted twisting. Designed in collaboration with Ned Steinberger and Joe Satriani.
