The D'Addario Auto Lock guitar strap is a simple, integrative strap locking system designed for your performance. The latch is spring-loaded, so it automatically tightens on the strap button and doesn't release unless you want it to. The D'Addario auto-locking guitar strap works with most strap knobs on the market. Designed for players of all kinds, D'Addario woven straps offer designs that will please even the most demanding players. From iconic themes to unique patterns and illustrations, these durable straps are sure to accentuate any guitar and are adjustable from 35" to 59.5" long.
