We light the evergreen tree in a cul de sac during the holidays and need to protect the power cord where it crosses the blacktop. After ruining several cords over the years from having delivery trucks and mail trucks running over them I decided to try these. Only issue I had was needing to keep the cord in the channel. I solved this by putting duct tape to cover the channel to keep the cord in place. Worked great and cord was fully protected.
