The D'Addario Comfort Leather Auto Lock guitar strap provides you a simple, integrated strap locking system for your performances. Simply slide the strap end over your guitar's strap buttons and it automatically locks in place—it's that easy. The gray latch is spring-loaded so it clamps down on the strap button and won't release until you want it to. Just push up on the gray latch, slide off the end and the strap is removed. It works with most strap buttons. Designed in partnership with Ned Steinberger, the Comfort Leather Auto Lock guitar strap is available in 2.5'' and 3'' widths so you can choose the size that suits your guitar and comfort needs.
