Dog Agility Bar Jump Each jump is fully adjustable and contains one jump bar with a set of jump cups to rest the bar. Assembly takes no tools and only takes about a minute to put together. Made from 3/4" furniture grade PVC. Great for all breeds small and large, novice to expert. Jump Cups Included Each jump comes with one adjustable jump bar and a set of jump cups. The jump cups snap and slide up or down the bar to adjust height. You can lower the bar for a beginner starting at about 3 inches from the ground and raise it up to roughly 30" for the more advanced jumper. The jump cups are designed so the jump bar is displaced if the dog hits is to limit injury. Easy Assembly Assembly of each bar jump takes about a minute. Each jump requires no tools to assemble and only contains six pieces that are color coded for simple assembly. Multiple Jumps Multiple jumps mean you can set up a large course in your back yard or local park. They can be placed in a line or staggered between other obstacles. The possibilities are endless.
