The D'Addario Dual-Lock Strap Lock provides a low-cost
alternative to strap security for additional instrument
protection. Without need of modification, the Dual-Lock clips
onto your existing strap button to prevent your strap from
releasing accidentally. Additionally, the Dual-Lock can be
clipped onto your instrument cable, securing your cable to your
instrument to prevent the plug from being pulled unintentionally
from the input jack.
