Give your trampoline added security with the 12-Foot Safety Enclosure. The enclosure is made from a non-abrasive polyethylene mesh netting that is tightly woven to prevent fingers and toes from getting caught. The netting encloses the entire trampoline, and the durable, five foot padded steel masts keep the netting taught and secure. The entrance opens and closes with an easy-to-use zipper, and the entire enclosure is quick and easy to set up. This enclosure also passes all ASTM safety requirements.
