Review on Circo 12-EZ Light Grip ABS Snap Clamp 0.75 Inch X 4 Inches Wide, Pack of 10 by Eric Hanson

These clamps worked very well for a year attaching PE reinforced plastic to an 8x16 greenhouse PVC frame. I've also used them to hold polyethylene to door frames. The reinforced polyethylene eventually ripped in a 70 mph storm and I had to move it to plug the holes until a more permanent greenhouse was built and salvaged. Now I am using them again to attach the shading fabric to the PVC pipe in the rolled up greenhouse shading system. The clamps now look old and dirty, but work perfectly almost two years later. I had to buy them back several times to get enough for the original project and I used about 70 of them including doors and door frames.
