Across
- 4. heavy/When the arbor weight is greater than the weight below the loft blocks.
- 8. pulley for hoisting or hauling with a grooved rim for retaining a wire rope.

- 15. Retardant/label means retardant chemical has been added. These fabrics need FR upkeep.
- 16. heavy/When the load is greater than the arbor weight directly below the head block.
- 17. purchase/A counterweight system where 1 pound of weight over the stage is matched by 1 pound of weight on the arbor. Battens move 1 foot for every foot the arbor moves.
- 19. plate/Thin flat bars on an arbor used to mark balanced loads.
- 21. consisting of two eyes and a threaded rod which is adjustable, allowing hanging scenery to be raised or lowered to the precise height needed.
- 25. loft/The space between the roof and the performance area that is not visible to the audience.
- 28. rope/wire cable, typically around ⅛” used for lifting scenic elements, or attaching battens to rigging. (also known as aircraft cable)
- 30. eyepiece used for the end of the weir rope to provide a location for attaching other hardware.
- 31. link/ a connector used to link or terminate a chain
- 32. hung/ Battens or items directly fixed to the structure or attached at a fixed elevation using chain, rods, or cable.
- 33. set/One unit of a counterweight system consisting of one or more lift lines that can work together as a group for hoisting wider scenery.
- 35. lock/This lever holds the batten in position when the load is balanced.
- 36. border that is part of the proscenium opening.
- 40. curtain/A curtain that travels straight up and down.
- 42. balance/When the arbor weight and batten load are equal.
- 43. (and keeper)/a piece of hardware that is attached to the top of a flat that provides a ring for hanging
- 44. block/A pulley mounted to the gridiron of a performance space or to the building’s support steel, to support the lift lines and change their direction between the load (on the batten) and the head block.
- 46. purchase/A counterweight system where 1 pound of weight over the stage requires 2 pounds of weight on the arbor. Battens move 2 feet for every 1 foot the arbor moves.
- 47. Press/often called by the brand name Nico used to clamp a sleeve around wire rope to make a secure rope.
- 48. cradle/A special effect using muslin rigged onto two adjacent battens, filled with artificial snow.
- 49. motors/A type of motorized rigging used to lift large items typically found in arena rigging.
- 50. shaft/A part of a motorized rigging system that rotates on a motor to control batten movement.
- 51. woven fabric that appears solid when lit from the front, but transparent when lit from behind.
- 52. rail/The horizontal metal rail with a row of rope locks.
Down
- 1. strong fiber derived from the Philippine abaca plant.
- 2. collection of beams that provide support for the head and loft blocks.
- 3. connector used in climbing that is spring loaded and sometimes used in rigging.
- 5. clamp for attaching two pieces to each other, often fixed or on a swivel
- 6. system/A rigging system composed of a batten or pipe over the stage space, suspended by cables connected to the arbor containing weights. This system allows scenery or equipment to be raised or lowered over the stage space.
- 7. carriage that holds the weights that counter balance the load on the batten.
- 10. that are dividend in the middle and travel on a track that open and close from the center.
- 11. legs that are the furthest downstage that make the proscenium opening appear smaller.
- 12. system/A rigging system that uses ropes and sandbags instead of counterweight arbors or other devices.
- 14. velvet-like curtain that has a dull finish and a thickness that absorbs and blocks sound and light.
- 18. line/The wire ropes that suspend the batten from the loft blocks.
- 19. rigging component consisting of a large loop and a threaded locking pin.
- 20. block/The pulley or block mounted to the building’s support steel that guides the wire rope between the arbor and loft blocks. The head block bears the full load of the line set and changes the direction of the lift lines.
- 22. canvas that is painted and hung as scenery. Very flexible ways to use in both size and rigging effects, such as full (entire stage), cut (for effects like trees/leaves) and roll (unwrapped for effect).
- 23. line/A ¾” rope which is attached to the top of the arbor and goes over the head block down to the user. An individual pulls on this rope in order to lower or raise a batten.
- 24. hoist/Similar to a chain motor, a type of rigging used for lifting large scenic elements, typically in arena rigging.
- 26. system/A theatrical rigging system that uses winches to move battens.
- 27. Flame Retardant/means the manufacturing of the fabric includes a fabric or process that lasts for the life of the fabric.
- 29. ring/The oval ring that surrounds the operating line and the rope lock to ensure that the rope lock is in a locked position.
- 34. gallery/The area near the grid where the arbor can be loaded with weight.
- 37. block/The return pulley for the operating line which is weighted to keep tension in the operating line.
- 38. rope, usually in shorter lengths, used for lifting scenery.
- 39. lighter, less expensive fabric that can be used instead of velour for curtains, but is also less effective at absorbing/blocking sound and light.
- 41. gallery/The area where the crew is able to lower or raise a batten.
- 45. operator/Stagehands hired to operate the rail/controls of a counterweight system. Also referred to as line operator.
- 52. total weight of the batten, scenery or lights, and the wire rope located below the loft blocks.
