Portable Quik Stiks tennis singles sticks keep your net up to tennis regulations! They are easy to transport, collapsible to 16, lightweight, and set up quickly. They allow you to keep the net at the regulation height of 42 inches when you play singles on a doubles court. Unlike traditional sticks, Quik-Stiks are easily fit into any tennis bag!Additionally, they offer a multi-purpose three-foot mark for placement at the center of the net for strap height. You can use the stick as a measuring device in order to determine the correct placement on the net (three feet from outside the singles court), place the top cable in the groove, and rotate the stick vertically. The stick expands fully to 42. The velcro strip also serves as a reminder to collect your Quik-Stiks after each practice session and match.
