T108 Parallel / P-Bar Box mat. P-Bar trainers have been around for a long time, from the wooden boxes of Eastern Europe to the current foam blocks, BUT none train beginning and advanced gymnastics skills as well as the By GMR Parallel Blocks. The P-bar Blocks feature a 1.5" diameter fiberglass rail which is padded with 3/4" Flextek foam and covered in 18oz. vinyl. The bar is 2.25" above the box surface which allows the gymnasts to wrap the bar with the whole hand. The bar is 60" long. Skills such as Stutz, Diamidov, Healy, Front and Back Toss as well as basic swings are easy to work. They are also great as a spotting block for beam, unevens or high bar.
