The Groove RT is an adjustable height range tee for mats! No more frustrations with standard rubber tees that don't adjust in height. The patent pending tees are for use with standard range mats and screw up or down to adjust to your desired height. Adjust the tee to your swing, not your swing to the tee!
Easy to Use - Inserts through tee opening in any standard mat
For use with thicker mats, specialty mats or simply for golfers who prefer to tee the ball up higher
