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

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!

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

Great product good to keep strap on guitar

I've been using these for years and have never had a problem with them on any size 'ukulele, including bari.

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.

If you don’t want to go so far as to use true strap locks,-or don’t want to spend the money, these work quite well and certainly won’t break your bank!

Nice sturdy quality. Bright red if that's the look you're going forward. Easy to install great fit when they damp in the sound of your strap ever so slightly.
