Abstract
A trench duct system of the type embedded in concrete floors or the like is provided for use in the distribution of electrical power, service and/or communication cables and wiring throughout a building. The system includes a plurality of trench duct sections which are interconnected to form a predetermined distribution layout. Each section of duct includes a cover plate which is removably supported by a pair of vertically adjustable side rails. The length of the cover plate and the length of each supporting side rail may or may not be the same and will depend upon the particular layout. The exposed surface of the cover plate is flush with the plane of the finished floor. Adjoining side rails, when in angular relation to one another, are interconnected by coupling members or connectors which maintain the continuity and stability of the system.
