Stuart, Charley's carries clips that will work. Here's a link:

I bought them to have on hand and for additional reinforcement where needed!

Thanks, Dawn. I ordered some. I definately need them...One of my side panels blew off over the weekend. I caulked some of the panels in, but not that one. Fortunately a neighbor was outside at the time and grabbed the panel for me.

My clips from Charley's finally arrived. They work very well on the HFGH. They are better than the ones that came with it. I think it would probably make sense to use all Charley's clips instead of the ones that come with the HFGH.
