Batten (theater)
In theaters, a batten is a long metal pipe suspended above the stage or audience from which lighting fixtures, theatrical scenery, and stage curtains may be hung. Battens that are located above a stage can usually be lowered to the stage or raised into a fly tower above the stage by a fly system.
Types
Electric
An electric is a batten that incorporates electrical cables above the pipe, often enclosed in a raceway. It typically has power cables for lights and DMX512 data cable for lighting control, and may also have audio cables for microphones. The cables emerge from one end of the batten and continue through a snake to dimmers, control boards, or patchbays. All cable plugs have identifying numbers printed on them so that they can be easily referenced by the lighting control system. Loaded electrics are among the heaviest types of battens, often weighing more than a thousand pounds.Electrics will often employ large loops of spring steel that extend outward to prevent adjacent battens from colliding with and damaging the lighting instruments. Electrics generally have an established trim height so that focusing is consistent. In some theaters, especially where battens are close together, a heat-resistant fabric is attached to the front of the electric to prevent heat from the lighting instruments from damaging nearby flown objects.
