The D’Addario Auto Lock Guitar Strap is the simplest
integrated strap locking system for your performance. Simply
slide the strap end over the guitar strap buttons and you are
locked in - it’s that easy. 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. The Auto Lock Guitar Strap was
designed in partnership with Ned Steinberger. These durable
straps are sure to accent any guitar and are adjustable from 30"
to 55" long.
