20 Pack - Snap Clamp ABS - Light Grip - 3/4 Inch x 4 Inch

ABS is nice and strong, for being so light weight. I use them for holding sheets to 3/4" PVC and they do that extremely well. I haven't had one break and I've put them on and also disassembled my projects, many times! I've had no problem doubling up the sheet material, as well, but I'm thinking that's around the reasonable limit. These things come in extremely handy. I don't plan on using them outside. I do think you'll need to get creative if using them in a high wind environment (like adding screws).These are a very good value. I've purchased a couple of 20 packs already and plan on buying more, for other PVC DIY projects.

These are super easy to snap on and have clung tight to the 1/2 inch aluminum conduit I used for my project.

I bought the 3/4" size. I have had these for just over a week now and I have to take some of them off and put them back on daily.They are very tight. I broke one when trying to put one on too fast in which there were at least 2 layers of plastic and with creases in the plastic. Thereafter I was careful how I put them on and take them off when there was more than 1 layer of plastic to attach.In retrospect, instead of 2 orders of 3/4", I would have ordered only 1 pack of 3/4" and then 1 pack of 1" since I need to use them on several layers of plastic in some cases. Of course, since I have not tried it, I do not know if 1" clips would have worked out, but I definitely would have given it a shot.

I love these clamps. They are so easy to use. I like to take my greenhouse down part way for the summer. It helps utilizing the rain to water, but still provides some protection for m tomatoes. It also allows me to recover the tomatoes if we get too much rain. Another way that I use these clamps is to place a shade cloth over the area against sun scald. Just love them.

I use these clips to hold plastic on small hoop houses (like a little greenhouse) in our garden. They are easy to put on AND take off. They also hold very tightly so the plastic and clip do not move around. They have little 'ribs' inside which I think helps them stay in place. I also have used them to hold shade cloth. Very pleased with these clips!

I am in the process of building a hoop house and have tested these clamps on the pvc pipe I will be using. They fit snugly and I am no longer worried about the plastic sagging or coming loose. I was immediately impressed with the quality of the clamps. They have a smooth finish inside and out which will help in preserving the plastic sheeting. A big thumbs up on these clamps and it is always awesome when a product exceeds your expectations.

These clamps have been a lifesaver in the garden as we build pvc frames to cover our raised garden beds. The clamps firmly hold greenhouse plastic or shade cloth but are removable without a lot of trouble. I will definitely be purchasing more!

The 3/4" size fits 1/2" PVC

We used them for our unheated greenhouse... The support and strength helped us with the structure re-enforcement. Best buy
