Buy 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 at desertcart UK. Review: Decent and functional - Good quality and value considering the expensive other options easy to assemble no problem with use and design ok too. Review: Actually does the job. - These give an additional level of confidence to what can only be described as the terrible strap attachment found on most guitars - designed to fail eventually. These aren't in the same league as the dedicated quick release devices such as Schaller strap locks, but if you are keeping the strap on the same guitar then they will help to keep the stap in place. Depending on the strap thickness and guitar mount these can be easy to fit or not! Found on one guitar had to unscrew the mount slightly, fit the flex lock strap and then tighten it up again. Well worth having if not using a quick release type device, plus here is no hole drilling etc. Would I buy again - Yes. ## Features - PROTECT YOUR GUITAR: D'Addario Flex Lock Strap Blocks–protecting your instrument and your performance.
