Double Channel Poly Lock and Spring Wire Greenhouse Plastic Attachment - 6 ft.


Double Poly Lock Channel is a great way to construct an all-metal Hip-Rail as a part of your High Tunnel, Hoop House, or Greenhouse. This material does not rust or decompose, so the life of the material is unparalleled.

Our Double Poly Lock Channel is superior to others due to its heavy gauge AND its rear slot which allows for bolt-and-nut connection to hoops using two-hole straps. This provides additional strength when used in conjunction with self-drilling TEK Screws. Connect multiple lengths of Channel to each other with the included Aluminum Splicer Plates.

Benefits of Our Double Channel Poly Lock

Pull your Greenhouse Plastic taught and secure. Using Spring Wire to attach plastic will extend the life of your greenhouse plastic by evenly distributing the pressure of securement along the entire perimeter of the plastic, which provides better protection from stresses put on your plastic from wind gusts.

Double Lock Channel

Good product overall. I have used this on both tunnels so far. We just installed the last piece of hip channel we had material for today, but we are 10' short from completing our tunnel so we have to order more. If I could re-design anything it would be the slot where the bolt heads slides in for a pipe strap install. I would also like to see a better splice plate design that uses the same channel as just mentioned. Will buy again to complete Tunnel #2.
