Abstract: A communication line such as an optical fiber or cable is attached along a wall, ceiling, trim piece, or other target surface inside of a building by laying out the line from an applicator tool. An outer surface of the line is placed in a temporarily tacky condition as the line is laid out from the tool along the target surface. The temporarily tacky condition of the line is due at least in part to an adhesive component that is pre-applied to the outer surface of the line. The adhesive component is activated by an agent or medium that is associated with the applicator tool. The line becomes non-tacky after it is attached to the target surface.
