These work great for the greenhouse/tunnel we constructed, however they can break if not handled carefully. We had about 6 snap in half.

I love how easy it was to fasten my shade structure to my hoop house using these clamps. They have held up to the windy days in Northern AZ.

These work pretty good. While they do rip the plastic in places they do hold it in place. I bought the 4 foot piece, and cut it into 3 inch pieces. I would buy these again if I need more.

We ordered the PVC fittings and clamps. They made it so easy to assemble a greenhouse cover for our tomatoes. The clamps hold securely but are removable so we will be able to remove the netting in the fall.

probably useful for shade cloths in green/hoop houses but DEFINITELY NOT for attaching the outside plastic, will not hold the plastic on in a wind,
