21 inches of setup room
An extended-length design gives ArmLock players room to find their preferred hand position.


ArmLock 21 is an extended 21-inch putter grip with a gradually tapered pistol-style profile. Red/White/Blue and White/Black/Silver are finish choices for the same model and length.
It is four inches longer than JumboFlat 17, but the shape also differs: ArmLock 21 has a gradual taper; JumboFlat 17 has a broad flat forearm-contact face. Match the grip to your stance and putter with your fitter rather than choosing by length alone.
