D'Addario Flex Lock Strap Blocks - Locks Straps In Place - Protect Your Instrument with No Modifications or Hardware - Easy to Attach - Set of 4 Blocks - Black

I had a new strap on my expensive new guitar that kept on popping off. These little rubber do dad’s did the trick. Haven’t had an issue since putting these on love it.

Work really good. I haven't put them to the test during the same kind of live performance I would do in my younger days, but they seem like you'd have to try your guts out to yank the strap off of the guitar.

Been playing guitar for 45 years, and never heard of these. Tim Lerch demonstrated a similar concept using the rubber washer from a bottle of Grolsh beer. These work great, are totally removable. Love them,

So far these have been great. I want sure if I would regret not just installing actual strap locks but so far these haven't fallen off or given me any problems, even on my very heavy 5 string bass.

If you don’t have a locking strap, these babies are a must have!!! Until you’ve had your strap fall off mid gig, you don’t know the terror of that occurring. You can avoid all of that with this product. Super easy to use. They come in a 4 pack so you can pop them on a couple guitars at a time. Built with sturdy rubber, I don’t think these blocks are falling apart, you’ll end up losing them before anything. Great design, they seem to fit on all guitars for the most part. They fit my acoustic, my bass and my guitars effortlessly and they’re not loose at all. Highly recommended!

These are stiff to begin with. Make sure you warm these in your hands so they are pliable. So far so good. Not a 5 because it was not easy to attach to Taylor. Almost gave up. But now that it’s attached it seems really secure.

It does just what it is supposed to. Keeps my guitar strap on.

Great product good to keep strap on guitar
