Save time by transporting just one box instead of multiple heavy boxes from storage! Simply rotate the steel-framed box for three different heights, 16"H, 19"H, and 22"H, to get a dynamic and explosive workout and a complete plyometrics box set with just one piece of equipment. Patent-pending, inlay rubber surfacing provides traction while permanently keeping the rubber, plywood, and steel secured. Each side of the box also features nonskid rubber feet for additional safety and protection for your floors. Patent Pending. 15 lb.
