Developed as an adjunct to the popular Accu-Roll, the Accu-Stroke functions like training wheels to immediately develop a sound putting stroke. The track is approximately 2’ long with on side beveled. Users can choose the flat side of the track for a straight back-and-through stroke, or use the angled side to allow the putter to come slightly inside the line. The high-density plastic material is unbendable and totally weatherproof ensuring a lifetime of use.
