ABSTRACT:
A net supporting standard for net games comprising a pair of elongated, thinwall, cylindrical plastic tubes diametrically sized so that one tube telescopes adjustably within the bore of the second or base tube. Each tube has a set of spaced holes formed in the associated tube wall. A hitch pin inserted through various combinations of overlying and mated holes locks the two tubes to establish a selectable length for the standard suitable for supporting a game net at three different heights appropriate for men's volleyball, women's volleyball, or badminton, as desired.
