Gauger Percussion Lug Lockerz Memory Lock (6-p)

* Keeps drums in tune by stopping the loosening of tension rods from sympathetic vibration. * Don't wear out like other lug locking devices. * Do not need to be removed if you want to change your drum's tuning. * Does not change the feel of drum tuning like some locking tension rods. * Can also be used on bottom heads without falling off.
