Yes, I looked at those. Trying to keep a small gap between the panels for air flow, but not so big so as to let mice build nests behind the panels. The ideal material would be 3" black anodized flat aluminum bar. But it is way too expensive. Need 80' of it.My other idea would be using clamps somehow, screwed into wood. If you shop around they can get pretty cheap. This is just an example I found at first glance. But it is a lot of panels so would probably still add up.
