How does this attach/stay in place?

I cut it to fit over the vents on the outside of my furnace door and tape the sides. This works so good. I can see when its starting to get dirty, so I know when to change it. It doesn't hamper air flow either.

How do I install on vent? Picture shows some type of tab on vent

I didn't see any tabs in my package. I used velcro in the corners on top the of vents. Then on a larger vent, I removed the vent and placed the material over the vent hole then replaced the vent cover. It's really simple and it holds in place.

I'm confused: in the product description, it says "NO FIBERGLASS", but under Specifications, Material Type it says: "Fiberglass" -- ?!?

Don't know for certain but I've worked with fiberglass and this doesn't feel like it. It feels more like a synthetic fiber, maybe a type of spun plastic. It could be the 'type' section only had a limited choice and none were correct so the seller just chose fiberglass.

What are the measuements of the unfolded sheet?

84 inches long by 28 inches wide.
