The fly system is used to move props and pieces of sets in and out of the stage area from above. There are ten main parts of the fly system.

Often operated in pairs for safety reasons, the fly system is very easy to use. To fly an object in, one person will release the brake, and both people will pull downwards on the front rope until the spike mark lines up with the brake. One person will watch the object being flown in (and what and who is under it!) while the other watches the counterweight arbor. When the spike mark reaches the appropriate spot, the brake is secured. To fly an object out, the process is repeated, only one person pulls up on the front rope while the other pulls down on the back rope until the counterweight arbor is close.
