The D’Addario Auto Lock Guitar Strap is the simplest, most convenient integrated strap locking system available. Just slide the strap ends over the guitar strap buttons and you're locked in—it’s that easy. The ends are spring-loaded so they automatically clamp down on the strap button and will not release until you push up on the latch and slide them off. The Auto Lock Guitar Strap was designed in partnership with Ned Steinberger and works with most strap buttons on most guitars.
