The idea is pretty simple. You take off the existing strap buttons, and fit the newly supplied buttons using the newly supplied screws. Thats the guitar end sorted.Then you secure the supplied lock to your strap, using the washer and the Hex Nut. Now when you clip the straplock onto the button, the strap cannot come loose from the button. To release the strap, pull the ball on the end of thr straplock away from the guitar (while holding onto the guitar carfeully of course!) and slide the lock off the strap button. Good instruments don't come cheap as it is, for just a few quid why not protect the investment which you've already made?
