Hole location, size, and orientation (vertical or horizontal) must be well specified. A template can assist in providing this data. The example template illustrated is for a 6-pin tangent crossarm with a symmetric pattern and horizontal brace bolt holes. This template can be adapted to other symmetrical configurations such as 2-pin and 4-pin. Please provide separate sketches for alley construction, unbalanced framing or offset patterns.
