The improvement comprises a base portion for attaching the bracket to a utility pole, a pair of spaced apart flanges for supporting a crossarm, and a pair of arcuate mounting seats providing contact surfaces with outer edges of the crossarm to minimize deformation of the crossarm.

Mounting seats further minimize deformation of the crossarm by contacting the crossarm at its outer edge rather than the entire surface area.
