Weighing in at just 40lbs., this standard is not just for the 2" socket but can be fitted to 3" and 4" sockets with adaptors. Compression and tension stresses have been analyzed, resulting in this lightweight modernistic design that will remain vertical and flex free at international level volleyball. Each pair of standards provides easy height adjustments with 6 increments, from 6' for girls elementary to 8'3.5" for men's pro practice. 3 year limited warranty. Posts are supplied with custom form fitting pads that can remain on post during storage. Recommended to be used with America's Cup pre-tensioned patented volleyball net, #2-113.
