A knock down tapered pole for power-line use comprising a series of vertically connected sections, each of said sections being comprised, as follows: a spaced series of generally U-shaped bent-corner plates of uniform cross-sectional thickness, said corner plates having divergently extending marginal legs with holes positioned in longitudinal spaced relation along each of said margins, a plurality of spaced trapezoidal-shaped flat plates each positioned between a pair of said corner plates, the flat plates each having nonparallel marginal edges which converge in the direction extending towards a top end of the pole and which diverge in the direction extending towards a lower end of the pole, and a series of fasteners cooperable with said holes joining opposite margins of said flat plates along said nonparallel marginal edges in assembled relation with said marginal legs of said corner plates.
