Secure the guy line if the turnbuckle breaks
Prevent loosening of the turnbuckle from vibration✓Richtige Antwort

Erklärung
Wind and vibration can slowly unscrew a turnbuckle and let a guy line go slack, which changes the tension pattern that keeps the tower standing. A safety wire threaded through the turnbuckle body and frame locks it so it cannot turn.
