Gorilla Zipper Door Containment Zipper Heavy-Duty 2 Pack: Premium Door Sealing Solution Review

Great product. The only thing missing is a piece to cut through the plastic behind the zipper, but the knife works great.

I ordered two boxes of two. In one of the boxes there was only a zipper. It's hard to understand why someone didn't notice that one of the drawers was half empty!

It's the end of March and I've used this zip to add another wide door to my existing plastic covered greenhouse. After a week of torrential downpours, the flash is holding on.

It works well with sticking to plastic which means you'd better make sure it's where you want it before sticking it to plastic because it won't peel off without that ripping plastic lol. I tried sticking it on thick mylar and it kept coming off. It works on most surfaces as long as they aren't too smooth. You may need to use super glue. Although of course it works well with plastic.

Installed literally 1 month ago (built on greenhouse and pond tent with 6 mil greenhouse viscosity in early November. I have to say there were no instructions, no advanced experience, nothing but a bag) and 2 zippers. After 3 weeks it was noticed that one side of the pull tab at the top of the zipper was losing support. Yesterday I went to the service pond and found that the glue did not work at all, the stickiness is zero, the flash was on the bottom. 25F and 72F since installation Daily highs
