Update your playground with the Large Extra Heavy Duty 3 Prong Tire Swivel. The square plate is easily secured into a wood beam or post making initial installation and future maintenance simple. The tire swivel itself features three loops to keep chains separate to prevent tangling. The boot over the universal joint keeps little fingers from being pinch and protects the joint from the elements. Finally, the support plate is a square maximizing the surface area that it connects with.
For a slightly smaller connecting plate, check out the Extra Heavy Duty 3 Prong Tire Swivel.
