Action Dome™ Obstacle Kits includes all the move-through shapes that are offered individual. Just snap-together the tubular sections and then insert them into the Dome center holes to create six 34” tall hi-impact Posts; six 24” high Arches; six 30” diameter Hoops, or six 12” high Hurdles. All connected shapes are light and sting-free on impact. Domes are great indoors or out, but add-ons items are best suited for indoor play. The obstacle shapes are anchored by Action Domes™, which are sold separately in dozens in COLORZ.
