Pulling cables through suspended ceilings or small passageways is time consuming, difficult, and often dangerous to workers. The small areas often contain dangerous materials, voltage sources, vapors, or particles which can present hazards to those doing the work and those in the immediate area. Suspended ceilings, for example, require removal of many panels to gain access for the passing of pull cords, or "snakes" as they are sometimes called, which are then used to pull the heavier cables through. This procedure often allows dust, insulating material, or other contaminants to escape from the closed ceiling area and enter the rooms below. It also often results in the disruption of the workers in the offices or labs below the tiles which must be removed.
