No concrete required with this Lifetime 52 inch portable basketball hoop! This XL Portable Basketball System is designed with a 52 inch shatter proof backboard of Makrolon™® polycarbonate with Slam-It® rim and easy Front Adjust® height adjustment feature. The powder-coated steel pole is rust resistant and the pro-glass look backboard is UV-protected to resist discoloration. Just fill the base with sand or water to provide the necessary stability. Water is easier to manage as far as filling, moving, and draining the base. This portable basketball system has been tested to withstand up to 40 mph winds when properly filled with water. Sand provides more rigidity and is more suitable if you want your system to withstand higher winds, aggressive play, and leaking. Made in the USA from US and imported parts. Assembly required. Covered by a 5 yr. warranty in US and Canada.
