  • Publication number: 20140137974
    Abstract: An duct for distributing transmission media is described herein. The duct has an elongated main body having a length and a lengthwise bore formed through the elongated main body. The elongated main body includes a generally flat bottom portion disposed adjacent to the bore and at least one strength member disposed lengthwise within the elongated main body. The at least one strength member defines a control surface disposed parallel to the flat bottom portion and intersecting the bore of the duct such that the transmission media longitudinally intersect with the control surface over a strained portion of the elongated main body when in a stressed state. An adhesive layer is disposed on an external surface of the flat bottom portion.
