Patent attributes
T-shaped raceway base components are provided of standard length, and the flat back plate portions are scored at intervals. The forwardly projecting web portion of the T-shaped base has a leading edge that defines opposed flanges for receiving cover components, and these covers also mount to the top and bottom marginal edges of the back plate. These marginal edges and the flange defining leading edge provide regions of continuity for the raceway base to give the base sufficient stiffness so the web itself can be slotted at each of the same intervals where the lines of weakening are provided. To sever the base at one of these intervals, the installer can snip these three edge regions of continuity, and flex the base to separate it at a selected interval location. The same concept is used to provide the same advantage for raceway base coupling elements that can be used to join raceway components with gaps therebetween.
