ABSTRACT:
An extendable channel unit such as molding unit (21) has a pair of telescopically arranged relatively extendable conduits (55, 75) with a conductor (22) interconnected in conductive relation between the conduits, with an intermediate section (137) of the conductor effective to accommodate the relative extension of the conduits. The intermediate section may include a sinuous configuration (133) or expandable coils (139). The channel unit may be installed along a wall (145) or other surface for decoratively covering the installation of the conductor for connection with an operated device (153). The channel unit may be installed into a ramp (163) when installed along a floor, such as within a doorway (171).
