This Tennis Caution Tape is ideal for QuickStart Tennis, easily creating 6 playing areas for 12 children in a single tennis court (tie from back fence to back fence and run through the net with the children hitting from alley to alley). Also great to quickly create a net in your driveway or back yard by tying it between two chairs or trees. 3 mil thickness is durable. Use and reuse or throw away. Another idea for use is to tie between two side fences to raise the height of the net. Or, be even more creative and tie from side fence to side fence at different heights to practice shots with different arcs and depths. 3-inch wide x 1,000 feet per roll. Highest quality tape available.
