Stops are?

Stops are?

• A. Metal pieces that prevent fly from extending too far
• B. The parts that hold the ladder in car
• C. The bolts that attach rungs
• D. The label plates on ladder

Answer: (A)

Stops are metal pieces built into the ladder rails that physically prevent the fly (the extended outer section) from extending beyond a safe limit. As you set up an extension ladder, the stops work with the locking mechanism to hold the ladder at the chosen length and keep the sections aligned. This limit prevents overextension, which could make the ladder unstable, cause the sections to slip or separate, or lead to a fall. Other described parts—those that hold the ladder in a vehicle, the bolts that attach rungs, or the label plates—serve different functions and do not control how far the fly can extend.
