32 Piece Clamp, 20mm Clamp for 1/2 Inch PVC Pipe, Clamp for PVC Pipe Greenhouses, Light Grip ABS Snap Clamp, for Row Covers, Shelters, Bird Protection,2.4 Inches White (for 1/2 Inch PVC Pipe)

Works well when clamping poly plastic to the PVC.

I had my hoops out of 1/2in PVC pipe and these make attaching sun shade, frost cloth, or plastic easy. They go on easy and remove easy too. I love this product.

I buy clamps every year to replace the ones damaged by prolonged sun exposure on my greenhouse. They are needed on shade cloth & plastic.

Super disappointed in these. Instead of buying a cuffing a pvc pipe one size up to make my own clamps i figured this would save time. Well, these simply can't hold two pieces of thicker plastic together over standard pvc. They are more of a C shape instead of say 70% of a circle, which if they were then how thin they are would have been fine but since it's thin and doesn't wrap enough they just fly off and pop off. Honestly feel like the sun too will just cause cracking with how thin they are and just how they feel uncoated. Don't recommend these

The diameter is correct for 1/2 white PVC but the clips themselves are too short, which means they don't stay licked in but pop off as soon as the wind gets up. Very limited usefulness. Engineers must have just scraped through the final exams

I was excited when I got these for my hoop house tunnel and I realized the quality is not good enough.They break in half very easily as seen on the photo. Sad to keep buying plastic that's not made properly.
