______ crossarms are frequently used at dead-ends, corners, and angles.

When a conductor ends or makes a turn, the mechanical load on the pole increases because the line tension pulls in multiple directions and needs more space for insulators and hardware. Using two crossarms provides extra strength and clearance: it distributes the tension over a larger surface, keeps insulators and hardware properly spaced, and provides enough room for the conductor to change direction without risk of rubbing or arcing. That added capacity is why two crossarms are commonly used at dead-ends, corners, and angles. A single crossarm often isn’t enough to handle the higher load and required clearances, while three or four crossarms would add unnecessary complexity for this application.
