Spot rigging

In technical theater, spot rigging is the practice of using a fly system to fly something specific for a show which does not use the venue's standard rigging. For example, flying scenery on an ordinary batten would not qualify as spot rigging; flying a chandelier on a dedicated line would be. Likewise, if a wall were being flown in on a batten which was installed at an angle neither parallel nor perpendicular to the proscenium line, it would qualify as spot rigging, because custom setting of lift lines would be required.
