Hot-dipped, galvanized steel ground sleeves hold 4-1/2" or 5-9/16" OD gooseneck posts. They allow for up to 4" of crossbar height adjustment to reach the official 10'H. A built-in anti-rotation device keeps posts firmly in place. Two ground sleeves are required per field. Each requires at least a 30" dia x 53" deep excavation for installation. For use only with Bison goalposts.
