Completely pads the steel floor foot of the balance beam leg and attaches with hook and loop to landing mats under and at the end of the beam to make one seamless system. Outside cover is sewn with heavy 18 oz. vinyl and nylon thread. The inside body is composed completely of cross-linked polyethylene foam to prevent any possible penetration and to provide the ultimate level of safety and protection. System consists of four individual pads. Each pair of pads creates 6" X 90" covering area so that the pads flush up perfectly with a 7.5' wide landing mat. Please specify brand of balance beam when ordering, as dimensions of the beam legs vary.
