Note:
BROOKS solid sawn crossarms are manufactured only after the rough cut stock has been kiln dried to industry accepted moisture levels. Only after the stock has become dimensionally stable is it surfaced to a finished size and produced into crossarms. This is an essential step in producing quality crossarms which minimizes further dimensional change after installation.
3.Solid Sawn or Glued Laminated
BROOKS manufactures distribution crossarms only from coast region Douglas fir in either traditional solid sawn or glued laminated stock. Douglas fir lumber from other regions does not treat to required specification.
