Finally a way to train and play while containing all those stray shots! the NHL fiber-tech goal Backstop quickly and easily assembles to any 72 inch steel goal with a vertical back support brace. Covering an area of 12' x 7', this goal add-on allows you to spend more time playing Hockey and less time chasing balls and pucks down the street! also great for protecting cars & garage doors from those slap shots that elevate just a bit too much! the Backstop was designed for use with all street & roller Hockey balls and pucks, and sets up and breaks down in minutes. Turn your goal into the ultimate training tool & let those shots fly.
