The Roto-Grip from Grover

Grover Musical Products’ Roto-Grip (505F Series) allows you to upgrade your vintage Fender tuners to a more modern style locking tuner without making any modifications to your guitar. The overlapping ear design allows you to utilize the existing screw holes and the use of push in bushings, rather than screw in, means no modifications have to be made to the post holes. Available finishes include nickel, chrome, and gold.
