Hi all, I just installed a bimini top on my new to me Challenger 1800. I'm thinking about using some velcro strips to hold the back support rod against the other rods when I lay the top back. Will try placing it where the rod comes in contact with the boat or just to the side of the other rods. I have some of the velcro strips you use to tie your stereo or video cables together with that might work. Will let you know how that works out. Good luck..
