The
grid is the supporting structure for a theatrical
rigging system and its many components. It is usually steel but can also be made of wood. The grid is generally found at the top of the
flyhouse. When designing for any stage space it is important to consider the grid height in your designs as this indcates the maximum height off of the stage deck which any piece of
scenery can be flown.
Ideally, the grid is easily accessible and there is enough space between the top of the grid and the roof of the flyhouse for one to walk on top of the grid. This allows for the rigger to easily inspect the grid and all of the loft blocks mounted on it for damage or wear. This is not the job for someone who has a fear of heights, however.
