Good afternoon, Port. I thought that I sent a couple of close up pictures to your email; maybe I didn't. Anyway, post #10 shows the side hardware (enlarge it) and it's the same on both sides. There is a pulley block at the top, a C-channel rail down the side, and a locking mechanism at the bottom. Then there is an elastic tie at the bottom corners. It raises and lowers much like a flag. I can get better photo's of the sides tomorrow and post them. I took it to an air brush artist and just got it back today.
