Nothing is more annoying to a guitarist than the strap suddenly falling away from your guitar on stage. Over time, the hole in the strap end can get stretched and loosen around the strap button until one day, you can only watch as your precious guitar hits the ground. The Dunlop 7036 Lok-strap solves this problem, quickly, simply and cheaply. You don't need any screws to secure it since it simply screws over the end of your strap and strap button to keep everything tight and secure.
