After tightening the shackle, it should be moused.

• A. Lashed
• B. Moused
• C. Secured
• D. Taped

Answer: (B)

After you tighten a shackle, you need to secure the pin so it can’t back out from vibration or load changes. This is done by mousing the shackle. Mousing means wrapping a short length of line (a mouse) around the pin and securing it, so the pin is prevented from loosening. The other terms don’t describe this specific practice: lashed is more about tying to something else, secured is too generic, and taped isn’t the standard method used on shackles. Mousing is the correct technique to keep the shackle pin from turning or loosening.
