This 7-position, quick-change, standard-duty square Ball Rebounder - new style with rounded edges. The easy-reach rebound ball shelf comes in handy during use, as does the 275 lb. weight capacity of this rebounder. With no clamps or screws, the 7-angle-position ball rebound platform makes for a tireless throwing partner and a fantastic (and stable) jogging, agility and balance stand. The Mini Rebounder is great to use for controlled power training, whether it's angled or flat.
