Soft-box setup keeps drooping down. Any help? I have a Neweer cb100c light thats attached to a 85cm soft-box. The setup always droops down even when I tighten the lock all the way. I have made some makeshift counterweight using a bag filled with water bottles but even then it droops down. Is there some kind of extension I can buy that could fix the problem? submitted by /u/richjunior…
