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.
