ABSTRACT:
A narrow elongated housing is provided constructed of an inner ribbed conduit which is overlaid with two layers of high strength rods. Each layer is contra-helically wrapped with opposing end portions compression secured in a termination chamber. The chamber is formed between a sleeve, which is attached to opposing ends of the conduit, and an outer termination enclosure. With the ends of each layer of rods in the chamber, the enclosure is either held stationary, or slid over the upper layers of rod ends. Concurrently, a wedge is either manually placed in the annular space between the layers and held stationary, or it is forced into the annular space between the layers. Any of the above combination of actions will force the rods against the sleeve and enclosure and frictionally secure them. The wedge may be a malleable metal so that it will cold flow about a portion of the rods. A flexible polymer covering is placed over the assembly to complete the housing.
