Great quality and perfect fit
We just put new metal roofs on our Garage and Shed. These are a perfect fit for sealing the ends of the metal roof. Will keep the insects and horizontal rain out! I am glad these don't have the adhesive. I prefer to set the roof with the end slightly loose, tuck these in where I want them then tighten down the outside screws.

Great quality
Everything about the product is great, however, be aware that there is no adhesive on them to stick them.

My husband said it’s good lol
I’m not entirely sure what this is to be honest, my husband made me order it lol I know it had to do with our roof but that’s as much as I know. It must of worked well cause 6 months later I ordered more for a different part of our roof. Anywho, I’ll give it 5 stars cause our roof no longer leaks. Yay.

USA made, non ventilated closure strip
Non ventilated. Kinda wish the glue was on the other side, to stick to the sheets, instead of the drip edge. But it sure worked out in the end. USA made!

I would buy this item again
I use these strips on my metal building and it’s been about two years now and so far they are doing what you’re supposed to. I would buy this item again.
