Keep it super secure and super simple with this D'Addario Auto Lock guitar strap. You simply splide the strap end over the buttons and you're already locked in! No extra hardware needed. 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. This strap has soft padded nylon material adjustable from 30-55" and is decorated with a stripe pattern.
