Superior Stretch StretchMax is the ultimate stretching tool for dancers and gymnasts. It has a welded chrome D-ring for easy slide and a soft secure door-strap, which eliminates door damage from large metal washers. It is made of soft, yet durable and strong 1-1/2-inch webbing. It won’t give you a rope burn that is usually seen in rougher strap webbing. It is less than 5 ounces making it easy to transport and store. It is a one size fits all.
