Abstract
A generally rectangular wiring raceway having the form of a moulding duct and capable of housing cable TV, telephone, computer, low voltage and other cables. The duct is designed such that it may be opened and closed for initial cable installation, for line inspections, servicing and the installation of additional cable. The raceway is comprised of an elongated back panel having a top leg and a bottom leg. The top leg has a snap engagement member and the bottom leg forms one part of a longitudinally extending hinge section. Additionally, an elongated front panel is provided. The front panel has a snap engagement member at its top for mating with the corresponding snap engagement member of the back panel. The front panel also has a longitudinally extending hinge member which mates with the corresponding longitudinally extending hinge section of the back panel. The hinge sections of both the back panel and front panel interlock such that when the duct is open the front panel lies in a plane substantially perpendicular to the back panel so that cables normally contained within the raceway may rest on and be supported by the inside of the front panel.
