The Putting Connection ''Deux" golf swing guide braces the arms together to create a perfect pendulum putting stroke where the arms, hands and putter are working together. Note: This putting swing guide is the updated version of the product we used to manufacture called the Putt-Lock Putting Connection. It is a copy of the original product but functions the same with strong braces and more precise adjustments. The product may be used for chipping and small pitch shots, but is ideally suited for putting.
