A method of connecting two raceways, comprising the steps of joining respective ends of first and second raceways at a first junction area so that the ends of the first and second raceways engage and form a miter joint at the first junction area, coupling a first cover fitting over the first junction area so that a portion of the first cover fitting engages each end, respectively, of the first and second raceways, joining respective ends of third and fourth raceways at a second junction area so that the ends of the third and fourth raceways are spaced from one another at the second junction area with a curved base disposed therebetween, and coupling a second cover fitting over the second junction area so that a portion of the second cover fitting engages each end of the third and fourth raceways, respectively.
