Patent attributes
An elongated sleeve structure for insertion and protection of elongated items within a duct is disclosed. The sleeve structure is formed from a flexible sleeve woven from warp and fill yarns to produce opposed layers in closely spaced relation. The layers have a common seamless edge and are joined along a second edge by a knit stitch formed by interlooping of successive traverses of the fill yarn which is common to both layers. The layers are of equal width and are resiliently separable into a spaced apart relationship defining a central space which accommodates the elongated items. A pull tape is positioned between the opposed layers for drawing the elongated items through the sleeve central space once the sleeve structure is positioned within the duct. Multiple sleeve structures may be joined together in an assembly using an attachment piece allowing a plurality of sleeve structures to be pulled simultaneously.
