CIRCOPACK 20 Pieces, 4" Long Snap Clamps Suitable For 1 Inch Schedule 40 Standard PVC Pipes Or 1-1/4" EMT, Furniture Grade, For DIY PVC Structures, E.g. PVC Greenhouse

After reading a few really negative reviews I expected these to be weak and cheap. They turned out effective and better! I bought one pack and was impressed so I bout two more for a total of 60 clips. Yesterday we had 50mph winds and the greenhouses with 12 mil plastic are fine.Now for the new buyer. If you want to save your plants you have to provide heat and spend good money on heavy plastic. Nobody can expect these clip or any clips can safe cheap thin plastic paint drop cloths.

The light grip clamps are perfect for quilt frames made with 1" schedule 40 PVC pipe. Love them. I saved a lot of money making my own quilt frame. The people who are giving a bad review are probably getting the light grip for projects like green houses that NEED a tight grip, (BOTH are available from this supplier). I have made green houses as well. I have always made my own clamps because I hadn't found these, making your own, it's hard to not get Sharp edges that cut into the plastic. I'll try some of these next time I make a cold frame or green house.

Great option for securing plastic to your pvc! Had one crack trying to take it off unfortunately. Very difficult to take off once you have them snapped in. They do the job though.

These clamps work very well for holding shade cloth on the 1" PVC pipes. I use the pipes to support the shade cloth over plants that get too much sun. The clamps are a big help.

I used these to hold down a tarp on my 1" PVC garden support system to fend off rains and storms during the winter in Florida. They held up great! They are incredibly strong and keep my tarps from being pulled away even with wind gusts of up to 30 mph! Have purchased these in the past, and will definitely purchase them again!

These work great for outdoor movie screens. We've built two outdoor movie screens using PVC pipe and a king size sheet. These come in handy for attaching the sheet to the PVC screen. They hold the sheet very well even in windy conditions. Can't think of a better or more cost effective way to accomplish this task.

Truly appreciate the ease with which these work! Was setting up a shelter for some of my plants utilizing PVC pipes & shade cloth. These clamps made securing the shade cloth effortless.

They work for me. Currently use them on a pvc greenhouse to secure greenhouse film/ cover
