Enjoy hassle-free net height adjustment using the telescopic 3” dia uprights with this system. Easily raise or lower to your liking, then place the stop pin in any of the laser-engraved height settings on each post. Adjusting tension is a breeze as well, thanks to a heavy-duty ratchet winch on one post. Easily set the competition net, sideline markers, and antennas via the sliding collar and pin-lock mechanism integrated into the upright. The 3” floor sleeves and cover plates minimize floor damage and provide optimal stability.
