Ernie Ball Strap Blocks – Red and Black – 4 Pack

Strap blocks are one of the simplest and most effective ways to keep your strap from slipping off during a performance. These flexible rubber rings fit over most standard strap buttons, creating a snug connection without modifying your guitar or drilling any holes.

This 4-pack includes red and black blocks, so you have spares on hand or can outfit two instruments. They install in seconds and hold securely through even the most energetic playing. If you have ever had a strap come loose at the worst possible moment, these are cheap insurance.
