I agree with Michael. The first time I tried the hair clip method on soft comb it went right through it. Plus trying to get them to stay on the bar with zip ties suck. Hair clips are the Macgyver method. If I gave you a box with assorted items to attach the comb you may come up with that. Plus hair clips are not that cheap. Hardware cloth can be attached to the bars ahead of time and gives you attachment points along the top of the comb. A frame is probably the best method, but a pain to make.
