Exhibit C 10ft Crossarm.pdf

This is a technical drilling guide specification document for REA (Recloser and Equipment Assembly) crossarms used in electrical utility infrastructure.

The document provides detailed dimensional specifications for drilling holes in three different crossarm types. Hole specifications are categorized by nominal size with corresponding GO and NO GO gauge sizes: Type A holes have a nominal size of 11/16 inches (GO: 5/8, NO GO: 3/4); Type B holes are 7/16 inches nominal (GO: 3/8, NO GO: 1/2); and Type C holes are 9/16 inches nominal (GO: 1/2, NO GO: 5/8). The guide includes technical notes establishing manufacturing tolerances: holes must be located within ±1/8 inch of specified positions, crossarm length must be within ±1/4 inch, cross-section tolerance is +1/8 inch and -0 inch at time of manufacture, and all holes must be drilled on the centerlines of crossarm faces. The document contains isometric technical drawings showing multiple crossarm assembly configurations (Types 14 and 22) with hole placement patterns and dimensional annotations. This specification document serves as a manufacturing and quality control reference for suppliers producing crossarm components meeting these defined tolerance requirements.
