Available at UKE Republic
If you want a simple, no-nonsense way to keep your strap securely in place—without modifying your instrument—the D’Addario Flex Lock Strap Blocks get the job done. Inspired by the classic Grolsch bottle-cap trick, these flexible rubber strap blocks slip right over your existing strap buttons to prevent accidental drops.
Made from durable, high-quality rubber, Flex Lock Strap Blocks fit most standard manufacturer end pins and stay put once installed. No tools, no drilling, no permanent changes—just snap them on and play with confidence. They work equally well on ukuleles, guitars, basses, and other strap-equipped instruments.
Each set includes four black strap blocks, so you can secure multiple instruments or keep spares in your case. Made in the USA, they’re an easy, affordable upgrade for players who want peace of mind on stage, at home, or on the go.
