Abstract
A supporting rail for supporting electrical fixtures or the like. The device comprises an extruded plastic elongate member which is formed at least in part by spaced inner and outer walls that are joined at spaced locations about the cross-sectional periphery of the member. The spaced walls define therebetween longitudinally extending hollow channels for carrying wires or the like, and the inner wall encloses an elongate inner chamber which is open along its length. A structurally rigid rail is thus provided but without requiring the use of substantially solid construction in the extruded rail.
