In ladder terminology, what is the fly section?

• A. Upper section of an extension ladder
• B. Bottom section of an extension ladder
• C. The rungs of a ladder
• D. The feet of a ladder

Answer: (A)

In extension ladders, the moving part that provides extra reach is called the fly section. It is the upper portion that slides out from the base (the lower, stationary part) to extend the ladder’s length. That’s why describing the fly section as the upper portion of an extension ladder fits best—it’s the part that moves and lengthens the ladder. The bottom portion stays in place as the base, the rungs are the steps you climb, and the feet are at the bottom for stability, so those terms don’t describe the flying, extending part.
