ABSTRACT:
Rotatable sleeves are disposed adjacent the ends of the crossbar of a goalpost. A stub is integrally formed with each of the sleeves and each stub protrudes through an opening in the crossbar. The opening in the crossbar is dimensioned to permit back to front movement of the stub and corresponding rotation of the sleeve until verticality of the stub and its associated upright is achieved. At that point, the sleeve is locked against further rotation by means of a tapping block previously installed in the sleeve and engaged with a serrated bolt through an appropriately dimensioned opening in the crossbar and corresponding holes in the sleeve. Once the bolts are tightened into the tapping block, the sleeve is drawn tightly against the interior surface of the crossbar, thereby locking the sleeve and the stub and the upright against further rotation.
