The Thomas Golf AT-90 left-handed mallet putter shares the red aluminum striking plate, square weight bars and black stealth finish of the AT-91. However, the weight distribution of this putter makes for a dynamically different feel. The square weight bars of the AT-90 are centered symmetrically just on the perimeter of the sweet spot. This allows for a more solid impact with the golf ball, resulting in a better roll and feel when making your putt. The square bars are also useful by allowing you to frame the ball within the bars, providing extra alignment when looking down at your putt. Assembled at 35” with a standard sized rubber putter grip.
