The Levy’s Strap Ring Block 4 Pack offers a simple, reliable way to help keep your guitar or bass strap securely attached without replacing or modifying your instrument’s existing strap buttons. Made from durable rubber, each ring slips over the strap button after the strap is installed, helping prevent the strap from accidentally working its way loose. The bright orange finish adds a little extra personality while making the blocks easy to spot in a gig bag or accessory case.
