Using these Fender Infinity Strap Locks is a breeze. First, find the right spot on your instrument strap for installation. Then, use the included mounting hardware to attach the locks. Once installed, you can easily adjust your instrument thanks to the 360-degree rotation. To release the strap, just use the side-pinch mechanism. When it comes to maintenance, keep them clean by wiping with a dry cloth regularly. Avoid exposing them to extreme moisture or heat as it may affect the steel. And always check the locks before each use to make sure they are securely in place for the best performance and instrument safety.
