OWLHAUS Polycarbonate Greenhouse Panel Connectors, U Channel 4mm, 20 Pack

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.

These fit both width and length. Exactly what i needed. No problem here. Other places sell for a LOT more but this was the cheapest and it also has great quality and quantity.

Exactly what we ordered

Impossible fit. I got the 8mm version of these H channels and they are an extremely tight fit. On the ground it is possible to get them onto the panels, but you need to pry the channels open with something. The 8mm version would probably work better with a 6mm panel, but are not appropriate for 8mm polycarbonate panels. Unfortunately, I had to purchase new channels after trying and failing to get these to work.

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

It connects 2 poly pannels together as expected. It is an absolute beast to slide them in though. Its a tight fit, but lay them in the sun on a warm day and it is much easier

Product was just what we needed to complete our project.

These might work ok on a roof. However using them on side walls of an existing greenhouse, don’t torture yourself!Save your money and use wooden strips, if you, have a wood framed greenhouse!!!!

Conviennent parfaitement très robustes

Wer sich das System ausgedacht hat....Bis man diese Schienen über die Platte bekommt.. Bin fast verzweifelt.. Am Ende mit Klebeband die Kante angeklebt und mit Spüli alles eingeseift, damit ging es einigermaßen..Ab sofort wird wieder besseres gekauft auch wenns mehr kostet..
