The Action Play Systems modular GaGa Ball Pit provides years of exercise and fun to your students. This kit includes twenty 48"W border panels that interlock to create a 26-foot pit. An ADA compliant door swings open on one heavy-duty caster, and locks in place with a hook-style latch. The durable recycled plastic panels can be used both indoors and out. Steel stanchions keep the panels raised 4" off the ground for easy pit cleaning. The pit can be permanently anchored outside if desired. APS GaGa Ball Pits are made in the USA.
