Surface raceway and method

A method comprising the following steps for aftermarket covering of lines adjacent a first surface of a structure:

• providing at-least-one first telescopic assembly having at least one first resilient tube and at-least-one second resilient tube;
• the at-least-one first resilient tube and the at-least-one second resilient tube having end-to-end openings with edges of the end-to-end openings having a predetermined peripheral relationship;
• the end-to-end openings being sized, shaped and positioned for peripheral compensation to provide resiliency for snugness of fit of the at-least-one second resilient tube inside of the at-least-one first resilient tube for telescopic length-adjustment of the at-least-one telescopic assembly;
• an inside periphery of at least the at-least-one second resilient tube being designed to receive lines;
• wherein said predetermined peripheral relationship of the end-to-end openings is peripheral overlap to provide resiliently variable perimeters of the at-least-one first resilient tube and the at-least-one second resilient tube;
• the at-least-one first resilient tube being an outside tube provisionally and the at-least-one second resilient tube being an inside tube provisionally;
• the peripheral overlap of the outside tube is decreased and the peripheral overlap of the inside tube is increased resiliently as necessary for telescopic assembly provisionally;
• inserting the lines through the at-least-one first telescopic assembly;
• and
• adjusting a length of the at-least-one first telescopic assembly telescopically to fit onto the first surface of the structure.
