Ernie Ball 4603 Strap Blocks 4-Pack - Black & Red

Ernie Ball 4603 Strap Blocks 4-Pack - Black & Red

The Ernie Ball 4603 Strap Blocks 4-Pack – Black & Red might just be one of the simplest upgrades you can make to your guitar or bass setup—but once you use them, you’ll wonder why every instrument doesn’t come with them already installed. Designed to keep your strap securely attached without the need for permanent hardware modifications, these handy little strap locks offer quick, reliable protection against one of every musician’s worst nightmares: the accidental strap slip.

Made from durable yet flexible rubber, the Strap Blocks fit snugly over most standard strap buttons to create a secure hold between your instrument and strap. Installation takes seconds, with no tools required, making them perfect for players who want extra peace of mind without drilling holes or fitting metal locking systems.

The black and red colour combination adds a subtle bit of personality too, whether you’re matching your stage setup or just like the classic Ernie Ball look. They’re small enough to keep in any gig bag or accessory pouch, and because this is a 4-pack, you’ll have enough for multiple guitars, basses, or backup spares for the road.

At Musicmaker, these are one of those deceptively simple accessories we recommend constantly—especially for gigging musicians, students, and anyone who values keeping their instrument safely attached while performing.
