Abstract
An extruded plastic housing of indefinite length contains an electrical conductor bar in a slot extending lengthwise of the housing. The bar is retained in the slot by a pair of ribs integral with the side walls of the slot and extending lengthwise thereof and projecting toward each other. The width of the bar is greater than the space between the ribs, but the housing is so formed that in assembling it and the bar the distance between the ribs can be increased temporarily by pressure of the bar against them to permit it to be moved rearwardly past the ribs, whereby the bar can be inserted from the front or outer side of the slot, thus permitting the use of a single conductor bar regardless of the number of housing units that may be disposed end to end to form the housing.
