- B.It connects the electrical cord
- C.It replaces the need for locking jaws
- D.It prevents the release handle from moving and the jaws from opening accidentally during travel
Correct answer
D. It prevents the release handle from moving and the jaws from opening accidentally during travel
Why
The latch is a backup that keeps vibration or a snagged handle from starting an unintended release. It only works if you close it after coupling and check it in your inspection.
