    Installing Spring Wire

    The lock channel is installed on baseboards, hip boards, and the end wall hoops on the top/outside edge of the hoop. Lock channels can be installed with wood screws on wooden base/hip boards or self-tapping screws into metal.

    For wood, we suggest pre-drilling holes for the wood screws.

    Ask a Question
    • do you sell the channel for the wiggle wire. If so how much is it and how long are they?

      Yes we sell Channel for the wiggle wire.  Lock Channel for Wiggle Wire

      We also sell it as a bundle Wiggle Wire Lock Channel Bundle

      Each component is 6.5 feet long.

    • I thought PVC was not good for your plastic so why PVC wiggle wire?

      The main reason to avoid PVC contact with the greenhouse plastic is the off-gassing and exposure on PVC hoops.

      The PVC coating on the wire doesn't have any off gassing. Primarily because it's a very thin coat on the wire and by the time we have it ready for sale any off gassing would have already happened.

      The PVC pipe is also problematic because of the rubbing on the pipe. The plastic will have some movement and be rubbing back and forth on the pvc pipe whereas on the spring wire is very static.

      The spring wire is also applied to the top of the plastic. So in that area the plastic has no exposure to the sun hence no UV damage. However where the PVC tubing is on the plastic is fully exposed to the UV exposure since the plastic sits on the outside of the PVC tubing.

    • How much comes in a pack? Does a 4 pack mean 4 individual pieces of wire?

      Yes a 4 pack includes 4 pieces of wire.

    • Do you sell a clamp/hook that allows for installing anti billow rope?

      No we do not sell those.  The only clamp we have is for shade cloth (link below)


    • Do you install these on every pipe, meaning every 4' across the whole hoop house?
