How do you load scenery onto a batten? First, you attach the scenery to the batten. Then, you load weights in the arbor. (Scenery should be heavier than the weights for the best operation.)

Safety Rules for the loading platform: Warn those onstage that a batten is coming in/going out Example: “Heads, first legs, coming in!” Watch where batten is going at all times while it’s moving Put the rope lock over the pin after task is completed
