The Dual-Lock Strap Lock provides a low-cost alternative to strap security. Without any modification to your guitar, the Dual-Lock clips onto your existing strap button to prevent your strap from accidentally releasing. It can also be clipped onto your instrument cable, securing your cable to your instrument and preventing the plug from being accidentally pulled if you, or someone else, steps on your cable.
