Keep your options open with a portable basketball hoop from Lifetime. Designed with a 35 gallon roller base that can be filled with sand or water to provide necessary stability. Water is easier to manage as far as filling, moving, and draining the base. System has been tested to withstand up to 40 mph winds when properly filled with water. Sand provides more rigidity, is more suitable if you want your system to withstand higher winds, aggressive play, and leaking. No concrete installation required! It features a clear, professional-looking 52" backboard that is virtually shatter proof. The Action Grip® height adjustment mechanism allows you to raise or lower the backboard from 7.5 to 10 feet with just a squeeze of the handle. This backboard has a Slam-It® rim that is constructed with double compression springs for spring back action. Powder-coated steel and UV-protected polycarbonate resists rusting, discoloration, and peeling. Full assembly required. Covered by a 5 yr. limited factory warranty in US and Canada.
