I was wanting a way to attach this to my gas fire pit, but it just sits on top. Does what it is supposed to and that is great! We had a storm roll though the other night and I had the glass on the fire pit. It's been on there for about a month or so now. Well the wind blew through between 70 and 100 MPH. It blew my gas grill over that sits under the deck. This wind guard on my gas fire pit did NOT move one inch, not even a quarter of an inch. I couldn't believe it! Glad I bought it!
