VIVOSUN2-Pack Heavy Duty Zipper, 3In. x 7Ft. Peel & Stick Zipper for Tarp, Double-Side Greenhouse Zipper Indoor Outdoor Dust Barriers Tent Zipper, Black

Great Product and works very well. As you can see from the photos I needed a new zipper for both sides. Because I have a different style green house, I did not know at first how to add a new one. But when I found VIVOSUN 2-Pack Zipper, 3In. x 7Ft. Peel & Stick Zipper on Amazon, I was very happy to order it. I started adding tape over the old zipper and with mins, both sides of the green house had the new zippers. I like the way I could review the video regarding the zipper. Outstanding and strong. Thank you.

Used on white mylar when building a new vegging grow room and worked amazing. a little light leak but not much more than any other zipper. very sticky backing that had zero issues staying on. so far 5/5 product. maybe just wish it maybe was a bit heavy duty like their grow tent zippers

Kept me from throwing out an old hardware bag and buying a new one.Just what I needed with a little sewing for strength.

a bit pricy but works well

I purchased these zippers as a replacement for one of those cheap powder-coated metal greenhouses whose cover disintegrated. I replaced it with greenhouse plastic and applied the zippers. In hindsight I should have measured out the plastic first and applied the zippers while the plastic was on a flat surface. However I applied them while the plastic was in a vertical position and didn't get them perfect but then again I didn't have anyone to help me that day. The zippers work great though they're a bit too long. I cut the zippers off where I needed them and pried the metal stop from the end of the zipper and repositioned it which took about 30 minutes to do both. They're holding up great and the only issue I have is that sometimes the cut plastic gets caught in the zipper but I think that's my fault as I was in the hurry when I cut the plastic. It been approximately three months and the greenhouse has experienced temperatures ranging from 20° to 115° and are still holding tight to the plastic. I'd definitely purchase again!
