ABSTRACT:
A crossarm system adapted to support power lines from a vertical pole. The crossarm system comprises a wooden crossarm member and first and second nail end plates. The wooden crossarm member defines upper, lower, inner, and outer surfaces and first and second end surfaces, a main bore, a plurality of pin bores, and at least one brace bore. Each nail end plate comprises a plate member defining an inner surface and an outer surface and a plurality of nail projections extending from the inner surface of the plate member. Each nail projection defines a width dimension. In use, the first and second nail end plates are displaced towards the first and second end surfaces, respectively, such that the nail projections enter the wooden crossarm member. The nail projections are arranged such that the width dimensions substantially prevent splitting of the ends of the crossarm member.
