First Team's Astro competition volleyball set makes lightweight, high performance volleyball equipment affordable! The Astro volleyball system is constructed of 3 1/2" x 1/4" wall high strength aluminum. Volleyball net is tensioned with our high grade precision wormgear crank with folding handle. First Team's wormgear net tensioning crank is exceptionally safe with no "backdrive" common with inferior net tensioners. Net height adjustments from 78" to 98" are quick and easy with Astro volleyball sets using our internal spring telescoping piston design.
