The set comes with two thick, leak-proof water bags that attach securely to the base with reinforced Velcro straps, adding steady weight to the outer posts to boost stability and prevent the net from sagging. No sand or drilling is needed-just fill the bags with water for quick, easy setup.Crafted from high-density, tear-resistant Pe material, the premium net is built to withstand outdoor elements and stays taut through intense play. Its adjustable length works for round, rectangular, irregular-shaped inground pools, reinforced fiberglass components and adjustable webbing on each side to keep the net tight and professional-grade for indoor or outdoor fun.
