This in-ground basketball system from Lifetime Products features a 44-inch Shatterproof Fusion® backboard with a Quick Adjust® height adjustment mechanism that adjusts from 8 to 10 feet high. It also includes a Classic Rim with an all-weather net and a 3.5-inch diameter round steel pole. So bring the arena home with a residential basketball system from Lifetime Products. Lifetime s in-ground basketball systems provide ultimate rigidity and take up less space than portable basketball systems. If you re concerned about the permanence of an in-ground system remember that while in-ground basketball hoops do require cement they need not be permanent if you use a ground sleeve. A ground sleeve allows for later removal of the pole if necessary.
