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

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.

Easy to lock in and looks like they belong. As described well packaged came earlier than stated. Would recommend both product and seller.

works very well and a very good price

Open mic at Dobbers Bar. Strap disconnected from the rear end of my new best AIO guitar. Damage avoided because I was sitting. Got these rubber keepers. Easy to use, brilliant simple design, cheap price. Keep your eight pound guitar from hitting the floor. Old straps dry out and get loose. These fix that.

I buy, sell and trade guitars often. Mostly high end name brands. For years I have been installing permanent strap locks on all my guitars, which generally involves drilling a bigger hole for the locks and attaching the other ends to my straps. But when I sell the guitars it is difficult to put the original strap buttons back on because the holes are too large unless I fill the holes with glue and tooth picks and then re-drill the hole so I usually leave them installed and also include the strap section so the buyer has the whole set. Those are fairly expensive and not something that increases the resale value of the guitar, so I take a small loss on the strap locks. A few years ago I discovered these washer type strap locks and they have worked great since, with no modifications needed to my guitars. I no longer jump around like Chuck Berry or George Thorogood on stage, ( age related aches and pains from years of wild stage antics) so i don't worry that these strap locks would pop off. If I was more energetic I don't know if I would expect these to hold up, hence the 4 star rating, but for the past few years of using these, I never dropped a guitar or had one pop off. These are on all my guitars now.

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,

Just put them on, it’s like two dollars and it will stop me from dropping your guitar. Goes on and off easily.

I always thought that securing a strap to a guitar involved special hardware and modifications, but this does the job quite nicely.
