The D’Addario Auto Lock Guitar Strap is a simple
integrative strap locking system built for your performance. The
latch is spring-loaded, so it automatically clamps down on the
strap button and will not 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.
