The D’Addario Auto Lock Guitar Strap is the simplest integrated strap locking system for your performance. Simply slide the strap end over the guitar strap buttons and you are locked in - it’s that easy. The grey latch is spring-loaded so it automatically clamps down on the strap button and will not release until you want it to. Just push up on the grey latch, slide off the end, and the strap is removed. Works with most strap buttons on the market. The Auto Lock Guitar Strap was designed in partnership with Ned Steinberger.
