I've just switched over from mesh panels to ProPanels after many satisfied years of the former. I wanted to be able to do indoor shows without having to use my tent frame, or any frame for that matter. It looked cheesy and I wanted a more professional look, but I digress.
What I would like to know from a users perspective is what works. What do I mean by what works? Well I bought cable hangers for the pro panels and found that they tend to slip and slide towards the middle with 2D work that is hung by wire. I didn't have that problem with the mesh panels as the hooks stuck in the holes and the work stayed there. I'm finding that the cable hangers tend to slide around toward the center on the wires and the work seems unstable. I'm wondering if I try their "hanger system" instead if those would be more stable, in other words they won't slide to the center of the wires and will keep the work level on the Pro Panels. So before I spend more money I'd like to hear from those of you that have experience with either or both of these systems I certainly would be interested in gaining your perspective or perhaps a way to keep the cable hangers from sliding around on 2D work that is hung on wire. I did put some heavy-duty duct tape folded over on the wire on the back of the frames to see if that would create some resistance for the cable hangers but that is not an ideal solution. I just checked on the work hanging in the garage and one photo was dangling at a precarious diagonal as the cable hanger had slid to the side.
As for using drapery hooks in the panel fabric, forget it, the work is too heavy and will cause the fabric to sag. Velcro around the edge of the work? Really? I don't think so, again the work is too heavy and it will cause wear on the fabric as well.
