The D’Addario Auto Lock Guitar Strap is a simple integrative strap locking system built for your performance. The latch on this comfortable, locking guitar strap is spring-loaded, so it automatically clamps down on the strap button and won’t release unless desired. The D'Addario Auto Lock Guitar Strap works with most strap buttons on the market. Available in a variety of materials and colors. Designed in collaboration with Ned Steinberger.
