Abstract
An articulated hollow arm is disclosed. The arm has a hollow center with an opening along the length of the arm. The hollow accepts electrical wires or tubes or mechanical wires depending on the application. A removable top is inserted into the opening and is designed to be retained by the mechanical interference between the top and the edges of the opening. Flanges or grooves may be placed to accommodate such retention of the top. In addition an external clip or an end piece may be used to retain the top while allowing the wires, etc. to emerge from either end. Any termination or connector at the ends of the wires, etc. do not have to fit through the hollow. Such wires, etc. can be removed, repaired and/or replaced via the elongated opening by removing the top. The top may be of a flexible material that provides strain relief for any cables.
