The Sport offers a professional look at an affordable price! The Sport's 4"x4" 11 ga. steel post is 50% heavier than any goal of its kind. Our one piece post design eliminates the potential for joint deterioration common with sectional type posts. The extension arm on the Sport is attached to the vertical post using two heavy duty U-bolts. Though the Sport is considered a "Fixed Height" goal, the U-bolts can be loosened allowing the arm to be re-attached at any given height along the post. The Sport Select Package features a 4" Square Post, Sport Extension Arm, 36"x60" Acrylic Backboard, Heavy Duty Flex Goal and Lifetime Limited warranty.
