Grover 406C6 Rotomatic Mini 6 in Line Self Locking Machine Heads, Chrome

Grover's patented locking tuners have eliminated the obstacles of other locking devices. Since there are no external mechanisms to initiate the locking action, the machine head's appearance is like any other. The entire locking mechanism is self-contained and self actuated. Arranged 6 in a line (Fender, Ibanez style headstocks).
