I needed to attach bird netting on my 4' tall, 4' x 8' hoop house for my veggie starts. These 1/2" clips are super strong & tight and will not move on the pvc pipe supports. The down side was they are so tight, to remove a clip to another location meant I ripped some of the bird netting so care is needing in putting on & taking off. To take off, I used a small headed standard screw driver on one long end and pried up to get it started. These clips work great! Here in Lake Havasu Arizona, we have super hot summers for 3 months (115-120+) so we'll see how they hold up. If I get a few years out of them, I will be happy.

These clips do a great job of holding both plastic and shade cover on my 1/2" PVC hoops. Nice and snug but not too hard to pull off when needed.

Even though I read the reviews that the clips don't fit 1/2" PVC, I purchased the clips. I should have listened to the other reviewers - they don't fit. Even with the plastic tripled the clips flipped off with the wind. The clips themselves seem sturdy enough to last for a couple of seasons.

These snap clamps work really well to hold row covers onto same size pvc hoops.

These are exactly what I needed for securing insect barrier to my raised beds!
