Here's a picture of our rope locks. http://img.photobucket.com/albums/v654/fiestakid88/2741620c.jpg Now the problem. Since we built this K-12 building, there is no longer and Auditorium, we have a combination Auditorium and Cafeteria. This has made our stage a rather high traffic place compared to how it used to be. Also, this is the first time we have ever had a fly system and we have other groups comming in to use the stage when I'm not around. I am worried that somebody will release the rope locks as they are walking by or perhaps mess with my counterwieghts. I am looking for a solution to locking the rope lock with a padlock. Is there something out there for my style of fly system? I know SECOA has theirs built so that a padlock can stop the handle from comming down. I could build something like it, but I would like to see if there is any product already being manufactured.
