Unlike many basketball goals, the Goalsetter System does not use a pole-in-the-ground method or "J" bolts assembly. Each Goalsetter System is anchored using our patented ground anchor hinge system. First, the 4' ground anchor is placed in a 4' deep hole (18" diameter) and secured using QuickCrete. When dry, the hinge system allows complete assembly of the Goalsetter goal before it is raised upright and bolted to the ground anchor.
