Patelai Greenhouse Clamps for Film Netting Tunnel Hoop, 40 pieces, 11 mm

They are hard to squeeze open/close and when the wind blows they move up on the arch. Other than that they worked great. I used them over my flowers and shrubs when we had freezing temperatures for a few days.

These are too thin to hold my tomato vines but are sturdy

These 16 mm clips hold deer netting to a 1/2 inch CPVC frame over my tomato plants. I didn't break any of the clips during installation but I could hear just a bit of a crack with some. They are not hinged and they're just barely flexible enough to slide over a half inch shaft. They probably won't last many seasons. The product would be improved it if were made with a more flexible plastic. I'm doing fine with them.

Nice thick plastic, but it is not a real clip. It holds the netting in place loosely, it slides down the hoop. Had to put a bunch of rocks to keep the netting in place.

Given these don’t actually shut - there is no true hinge - I think it is misleading to call them clamps. I imagine they will stay on place once fabric (only of a certain thickness tho) is between clip and support. But if you want to be able to “clip” them on to the support while you are moving or not using row cover etc, or keep them attached to poles when storing, they are useless. They fall right off. Sending them back.

I bought these along with garden poles and netting to use so I could cover a couple of vegetables I transplanted. I needed to keep them out of direct sun until the plants recovered from the transplant. I doubled the netting and the clamps held the netting to the poles perfectly. It does state in the description: "these 10mm/16mm clamps are only suitable for 10mm/16mm outer diameter pipe" so make sure they will fit your needs before purchasing.

Great value. Right fit. Poles must be thin to for work the netting in place too

I thought these clips were for 1/2” PVC pipe. They are way too small for my application, and I waited to try them. My fault. Should have checked as soon as I got them. I have no idea what I’ll use them for, but they won’t be useful for my original intended purpose, and they aren’t big enough to use with any of my plastic tubing. Waste of $, but my fault for not checking earlier.

Works great

These clips work well. No sure how they will weather outside.

Lesson learned.. never buy something from amazon without reading reviews. These "clips" are useless. They do not fit the standard pipe you would use for a greenhouse or hoop house. They don't have a spring either so I'd imagine they would be stretched easily and only be good for a one time use, that is if you have a thin enough tube/pipe you're using them on. Would not recommend. Not sure how this is a #1 seller in greenhouses.

They grab onto the round bar but they do not open. they are solid.

Product took about a week to arrive [no problem with that however]. Took chance on it fitting tube and it does. How long plastic will last in sun will have to be determined. Does what I need it to do and that is to clamp netting onto tubs.
