D'Addario Universal Strap Lock System, Black, by D'Addario

Having tried an alternative pattern system and found it rattled sometimes. I bought these to see if they improved matters. 1. They are easier to fit. However be careful if you are fitting to a smaller instrument than a guitar as the screws supplied may pierce right through. 2. They are not rattley like the other types. 3. They attach the strap to the button without fiddling about and are easier to detach when you pack away. They look a bit more stylish too. I believe the extra cost is worth the extra quality. Would be good if the buttons for the instrument were available as a separate item. Don't really need as many straps as I have instruments.

Good quality and very comfortable

Excellent product, very quick and easy to install, only tool required is screwdriver to replace the parts on the guitar which is a straightforward screw swap, feels extremely secure and heavy, sturdy metal parts, excellent would definitely buy again for future guitars / straps

Have these d'addario and schaller locks of different guitars. I personally feel the schaller locks are better, although the d'addario ones are decent enough.

Decent looking strap locks just be prepared to install them as it does involve unscrewing and screwing things into your guitar. Easy to install to the strap itself and once on are nice and sturdy.

Very surcureNot obvious there on your guitar strap so you’re not drawn to them while playingI would highly recommend these as I’ll be purchasing another set

If you like to have the Best , buy these you won’t regret the purchase, they are perfect for the job

Perfect strap locks, aesthetically the most pleasing I've seen on the market and the easiest to install and/or use
