The Bison 4 1/2" Heavy Duty Aluminum Fan Playground Basketball Hoop features a fan-shaped backboard made using durable, rust-free aluminum, and it has a white powder-coated finish with an orange shooter's square and border for a professional look. The galvanized pole and zinc plated hardware were designed for durability, and the double 5/8" steel rim has a no-fail netlock system that keeps the net securely attached during play. The pole gets buried 48 inches into the ground for a stable and secure setup, and it was designed with a 48" setback for maximum player safety.
