Abstract
Abstract The crossarm assembly is made of electrically nonconductive noncorrosive materials within an arcuate crossarm and a pair of legs for supporting the arcuate crossarm on a pole. Channelshaped brackets are used to secure the arcuate crossarm to each leg while a dowel pin is inserted within mating recesses of the crossarm and the support legs in order to position the crossarm and to resist the loading of the crossarm.
