Dogs/Pawls/Locks are?

Dogs/Pawls/Locks are?

• A. Locks that hold the fly section up
• B. The devices used to tie rope
• C. Protective caps on feet
• D. Handles for carrying

Answer: (A)

The concept being tested is how extension ladders stay safely at a chosen height. Dogs, pawls, and locks are the locking mechanism that holds the fly section up. When you extend the ladder, these devices engage with the rungs or notches and prevent the upper fly from sliding back down. They act as a catch or latch that you hear or feel when it seats into place, providing a secure stop so the ladder remains at the desired height while you’re climbing or working. Before use, you confirm the lock is fully engaged and won’t release under load, and you release it when you need to retract the fly. The other options describe different hardware (rope-ties, protective feet caps, or carrying handles) and aren’t about securing the extended ladder.
