Works similar to an aerial dog run except the system installs into the ground. Comes with two heavy duty corkscrews and all the hardware necessary to set up. High quality components for extreme weather durability and extended service life. This dog run will allow the dog to travel along a straight path rather than a circular area that would be achieved with just one corkscrew. The ground anchors will sit flush with the ground and the cable that runs along the ground can quickly be removed to allow for mowing without removing the ground anchors.
