Polycarbonate Greenhouse Panels (U Connectors) - 20 Pieces, 2ft Length, Prevent Dust, Rain & Moisture from Getting into Twin-Wall Panels, Fits 4mm (0.15 in) Panels (U Connectors 4mm-2ft)

These are perfect for the polycarbonate greenhouse panels that we purchased. I will be reviewing those later, if you want to go to that review to see which one's worked with these. I was a little concerned because the descriptions are hard to understand to know which ones will work. The ones that were linked to our polycarbonate panels we're not going to even ship until june, and we couldn't wait that long. So I took a gamble on these. And I'm glad I did. There are perfect our greenhouse roof is gorgeous. Everything's fit together perfectly. We did not have to cut any of these so I can't tell you how easy they are to cut. But functionally they are fantastic. They are great value for what you're getting. They seem nice and durable so far. I'm hoping they'll stand the test of time, but only time will tell that.One tip. If you're having issues getting them to slide onto your polycarbonate panels, dawn dish soap is your best friend. Just put a tiny bit on the edges of the polycarbonate panel and it'll slide right in.

Good quality,easy to work with

These panels come in a box that can allow dents in the panels that are on the outside.We used some of these 2’ x 4’ panels to make windows in the peak of our storage shed roof, instead of buying a window to let light in so you can see what you have inside.The panels are sturdy pretty clear and cut easily with a circular saw with the fine tooth blade in backwards. The connector strips(optional) work great putting them together. I would buy them again for other projects. They are sturdy. The thickness is 1/4”.

Perfect fit with a little work.

Decent quality hard to seal panels together

Easy to use and they perform as expected.

The dual wall design helps too minimize direct sunlight heat against my bonsi trust and they seem to love it.The product is easy to work with can be cut with a utility knife and cross cut with utility scissors.A good UV blocker even though translucent.Could not find any information con lateral strength Or wind resistance but the product seems to hold up well so far

Exactly what I ordered and came in good shape
