Review on 10-Pack of 1/2 Inch X 4 Inches Wide Snap Clamps in White for 1/2 PVC Pipe by Ronald Howlett

We live in Northern Michigan and every year a deadly frost hits us early and kills our plants once they are ready for production, so this year we decided to build a ring greenhouse. across the garden before the frost had time to hit the plants. These brackets work great! We used PVC tubing for the frame and these zip ties to attach the greenhouse plastic to the frame. They stayed in place through a couple of high wind thunderstorms. I read a review from someone who said you can't remove them once they are in place. They are difficult to remove, but possible. I removed some to place them differently. All I had to do was gently pry one end so I could free it. But once they snap, they're strong and keep the plastic where you need it. We bought 3 house sets with a 20' x 12' ring and ended up having a few spares. worth your money.
