description	A composite locking upright having low weight and great rigidity for installation into a playing surface with built-in sleeves. The composite locking upright supports and secures a net at a net playing height for athletic sports such as, volleyball, tennis, and badminton. The composite locking upright may have a composite tube, a metallic tube, an upper protective collar, a lower protective collar, and a locking tool. The composite tube may be made of a light-weight, fiber-reinforced composite. The metallic tube is extendable and retractable from the composite tube and may be made of a light-weight, rigid metal. The protective collars may protect the composite tube substantially preventing damage to the reinforcing fibers during installation and setup. The locking tool locks the metallic tube with respect to the composite tube and thereby fixes a net at a playing height.
