Roto-Grip Locking Super Rotomatics from Grover

Victoria Wasylak • 2021 Buyer's GuideAccessories • January 5, 2021

Grover’s new Roto-Grip Locking Super Rotomatics (509 Series) feature a three-step button and utilize the famous 18:1 Rotomatic design with a “thumb screw” mechanism, which locks the string into place. Insert the string through the post hole, wrap around once, then lock by tightening with the thumb screw. These are the perfect replacement for the most standard machine heads. Includes all mounting hardware. Available finishes include: nickel, black chrome, and gold.
