Grover 502C Roto-Grip Locking Rotomatics w/ 18:1 Gear Ratio, Chrome (6)

The Roto-Grip Locking Rotomatics® revolutionise string changing with their innovative thumb screw locking mechanism built into the renowned 18:1 Rotomatics® design. This clever engineering eliminates the frustration of slipping strings during tuning by securely locking each string in place once inserted through the post hole and wrapped around once.

Installation couldn’t be more straightforward – simply thread your string through the post hole, give it one wrap around the tuning post, then tighten the thumbscrew to lock it firmly in position. This streamlined process saves valuable time during string changes while ensuring rock-solid tuning stability.

These machine heads serve as an ideal replacement for most standard tuning pegs, maintaining compatibility with existing guitar setups. The complete package includes all necessary mounting hardware, making installation hassle-free for both professional techs and home enthusiasts alike.
