*Note: Due to spacing criteria, certain battens will bump the adjacent electric. There are 3 sets of “bumpers” for electrics to minimize the hanging up on nearby battens. It is not recommended hanging anything that needs to be brought in and out during a performance (particularly if done fast) on these battens. Drops, drapes, legs and borders can be removed or rearranged to suit show requirements. Grand drape, movie screen and electrics are NON- REMOVEABLE ASSETS. Early pre-planning of fly schedule is recommended for safe rigging. House TD has final authority on hanging schedule.
