Farm Plastic Supply - Spring Wire & Lock Channel - (20 Pack) - Steel 6.5 ft Spring Lock Track & U-Channel Bundle for Greenhouse Plastic Polyethylene Film or Shade Cloth

The channels went up easily and when it came time to put up the plastic it went very smoothly. The next day after installing the plastic we had a long wind advisory and the wiggle wire held the plastic up fine. BUT, the heavy rocks I put on the overlap at the bottom were moved by the high winds, but still held the plastic down enough so that I could re position them. I did not use staples to secure the plastic , but instead I bought a pack of long bungee cords to go around the middle of the entire chicken run to keep the plastic from blowing as much. (the bungee cords have not been delivered yet, so the winds happened before I could install them.) So far I'm happy with the purchase.

Lays flat in the hipboard and arch. Grooves in the center help keep the screw from wandering. Seems stronger than the last company I purchased from
