An arbor trap apparatus for use with a counterweight rigging system having at least one counterweight arbor. The apparatus may include a trap housing for attachment to a support structure, and at least one catch blade for attachment to the counterweight arbor. The catch blade may enter the trap housing as the counterweight arbor moves generally towards the trap housing, and the trap housing may engage the catch blade to prevent the counterweight arbor from moving generally away from the trap housing. The trap housing may transfer load from the counterweight arbor to the support structure and prevent a runaway.
