I bought the 1/2" version of this product and it worked great on the greenhouse/cold frames we have that are made with the 1/2" EMT conduit (OD is .706"). I also clipped our materials to the T-posts that support our EMT frame, this size won't open all the way around the T-post, but I clipped onto one of the protrusions. It will accommodate several layers of material, in our case we have poly-spun frost blanket covered with 4mil sheet plastic, and in some places had several folds of the plastic (at the corners). The clips open capaciously and the ends don't have to touch together in order to completely tightly grip whatever you put this on. The clips are made of what feel like high quality, thick ABS plastic, and the spring is thick and tight. You have to apply some muscle to open the clamp, but it's not brutal. I'm utterly thrilled with this product. The edges are smooth and I had no issues with them poking through either material. I've gone out and rearranged the clips while it was sunny to ventilate, then closed it all back up tight in later afternoon. Absolutely no issues, works wonderfully well. I plan to order more of these, and also order them in the larger size to have on hand. Versatile clip!I've used a couple of other products made for this type of application-- both the stainless-steel all metal clips and the clamps that are ABS plastic, about 4" long, and press on/pull off, both of which have problems (the metal tears material, and the press on clamps are hard to get on and off and actually can pop off in high winds, and they are pricey). The press-on type are good if you want to layer clips (because they are completely flat), and I used some of mine on the inner layers near the doorway opening to keep everything tight. But, these clips will be my first-line go-to for this function from here on out, and at this price point they are a no-brainer. These clips are fantastic and have helped me save my lettuces and greens through the 2024 arctic blast. I don't know how many seasons they'll last, but they have a good strong feel.

I wanted these to try and hold my tarp down and they fit the pipe I am using perfectly. They have a good tight grip and hold up pretty good in the wind so long at they are attached properly. I like these clamps.

Unfortunately, my pictures did not load into the gallery and it won’t give me that option again, but the picture I am showing shows after I’ve rolled up the frost cover and decided these were also great for holding it rolled up instead of flapping around in the wind like it usually does. These fit perfectly over the black pipes that I have along the ground for my potted plant watering system. I can clip them to objects as well or to the side of a pot to hold my frost roll down. I have a large group of potted citrus trees that are lined up along the railing of my deck, and I can cover all in one blanket of frost cover with these keeping it down, especially if there’s wind. You can attach them to branches although these are a little bit wide it will still clamp. The only thing I can say is that if you have a problem with strength in your hands, these are a little difficult to open. But I like the idea that they are plastic and don’t have teeth on them so they will not rip my frost covers . I thought it was more than I would need and was surprised I used every single one of them. I would definitely recommend them.

These work very well on 3/4 inch PVC, and though it says it can handle 1 inch PVC, I did not try it nor do I think they would work as well. I am using the to hold bird netting onto PVC frames I built for young trees and bushes. They are easy to use and seem sturdy. I will have to wait a few months to see what weather does to them, but they seem fine. Good value for the price.

These clips are working good for my netting on my cabbage plants. I get very strong winds and these clips are holding well

These clips are great, durable and very hardy and survives all weather.

I have a portable plant cover that's 4x4 feet that I put up in November and take down in March. These clips are great for that application. Easy to put on and take off that don't damage the plastic.

but they are so tough - you need two hands to open the clamp - i'm using them to cover over my blueberry bushes with tulle - very tough to open - but will do the job against those dang birds and the winds down here they call breezes.

These are amazing quality..I hope they will last me for many years.. I will buy these again.
