Description
D’Addario Strap Lock Blocks are a simple, reliable way to keep your guitar or bass strap securely in place without fitting any hardware. Supplied as a pack of four in classic black, they are ideal for players who want extra peace of mind during rehearsals, gigs, or practice at home. Whether you are a beginner with your first instrument, a working musician with a few favourite straps, or a tutor setting up classroom instruments, these compact blocks slip over the strap and button in seconds and hold fast. They offer an easy upgrade to the security of almost any strap, while remaining light, discreet and ready to use whenever you need them.
Built from flexible, durable rubber, each block stretches smoothly over the strap button then snaps back to form a snug, reliable barrier against accidental slips. The low profile design stays out of the way of your picking hand and does not interfere with strap comfort or movement. Unlike metal locks, there are no sharp edges and no tools required, so your instrument’s finish stays protected and your strap stays intact. It is a smarter step up from basic washers, engineered for everyday reliability and easy, repeatable use across multiple instruments.
For UK tuition and school settings, these blocks make quick work of securing classroom guitars and basses, helping reduce drops when instruments are passed between students. The four pack covers multiple straps or provides handy spares for peripatetic teachers and ensemble leaders. They are equally useful for regular practice, open mics and full gigs, adding low cost insurance that fits most standard strap buttons and common straps. With a neat black finish that blends into any stage setup, they deliver dependable, tool free security and great value for players and institutions alike.
