Using the D’Addario Auto Lock Guitar Strap is a breeze. First, find the strap buttons on your guitar. Slide the end of the strap over these buttons, and the spring-loaded grey latch will automatically lock it in place. When you're done playing and want to remove the strap, just push up on the grey latch and slide the end off. This strap is suitable for electric, acoustic, and bass guitars. It's adjustable from 43” to 55” long, so you can find the perfect length for your comfort. However, keep in mind that while it works with most strap buttons on the market, it won't work with end pin jacks or plastic strap buttons. As for maintenance, keep the leather clean by wiping it gently with a soft, dry cloth. Avoid getting it wet or exposing it to extreme temperatures, as this could damage the leather and the locking mechanism.
