20100021123 | Method and apparatus for allowing future installation of wires, cables, fibers and the like within a structure. - A method and apparatus for adding wires, cables, fibers or the like from an accessible part of a structure, such as an attic or crawlspace to an interior room from within the walls of the structure, includes installing a drop tube during the construction of the structure. The drop tube contains an insulating plug to prevent heated or cooled air from escaping prior to installing the wires, cables, fibers or the like. The drop tube is installed through an interior support and extends to an access point, typically behind an interior wall. The drop tube contains flexible barbs or fasteners that both secure the drop tube to like drop tubes so the desired length can be achieved and also allow for the insertion and securing of the drop tube into a penetration hole. At such time when the addition of wire, cable, fibers or the like is desired, the insulation plug is removed and the wires cables, fibers or the like are run through the installed drop tube from the accessible part of the structure to the point where they are needed. To make standard size drop tubes adaptable for penetrating materials of different widths, spacer sleeves can be inserted between the flexible barbs or fasteners and the material to be penetrated to create a secure fit. | 01-28-2010 |
