A real see-saw encounter saw the home side leading 27-21 entering the final minute before a nasty collision resulted in a lengthy delay and saw Matt Hema leave the ground in an ambulance.
Upon the restart, with Guernsey reduced to 14 men and Tring awarded a penalty, the visitors took a tap and kept the ball alive until influential fly half Tom Newton scored a converted try on the last play of the game to snatch victory.
