A structural member for a building includes a one-piece elongated support member having a pair of legs defining a trough therebetween and a projection extending into the trough from each of the legs. A one-piece elongated electrical raceway can be secured in the support member. The raceway includes a tubular housing having a pair of opposed side walls and open a pair of opposed end walls to define a channel extending between opposed ends of the housing such that an associated electrical conductor can extend through the housing. A first wing projects away from a first side wall of the tubular housing, and a second wing projects away from a second side wall of the tubular housing. The first and second wings flex to snap into a cooperating relationship with the projections of the support member to selectively secure the tubular housing in the support member trough.
