I have used this exact model for years on my Paul. They have never once come unhooked. I even demostarted to a friend by holding my les paul up and bouncing the guitar by the strap. Frankly I believe the strap would break before this let go.
One tip. Use a bit of treadlocker on the nut when you install on the strap. Keeps the nut from backing off.
This product is a very small investment for the safety of your valuable instrument. These strap buttons are fail-safe and lock your guitar to your strap. The included hardware should be a direct replacement for any standard strap buttons and install in a matter of minutes.
For installation on your strap, I would recommend using a solid leather strap and cutting out a hole the exact size of the receiving end of the lock. Sometimes compressing the lock onto a slotted strap can cause the leather to squeeze out of the sides. I have used these strap buttons (the same set) for over twenty years and have never had a failure. Worth every penny!
