This standard consists of specifications covering solid sawn-wood crossarms and braces manufactured from coastal Douglas-fir (Pseudotsuga menziesii – variety menziesii) grown in the West Coast region (i.e., from the summit area of the Cascade Mountains of Washington, Oregon, California, and British Columbia, Canada) to the Pacific Ocean; and from dense Southern pine of the following species: longleaf pine (Pinus palustris), shortleaf pine (Pinus echinata), loblolly pine (Pinus taeda), and slash pine (Pinus elliottii), as well as ground wire moulding manufactured from Douglas-fir (Pseudotsuga menziesii) or red oak (Quercus rubra group). The specifications are intended to cover communications crossarms, power crossarms, heavy-duty crossarms, heavy-duty braces, and ground wire moulding. Crossarms are intended primarily for use as beams. Heavy-duty crossarms may also be used as struts or columns in braced H-frames. Braces are used for tension and/or compression-bracing. Ground wire moulding is used to protect the ground wire at the base of the pole.
