9830704: Reese Towpower 7030400 Receiver Lock, 5/8 in Dia Shackle, Class: III, IV, Steel, Chrome

REESE® Towpower 5/8 in professional towing receiver locks are the most theft-resistant locks in the towing industry. Its great strength is derived from a patented locking design that does not require shaft diameter reductions which cause weak points. Weak points enable a thief to break the lock shaft more easily and escape with your trailer.

• Patented design eliminates weak points
• Ball bearing lock system prevents theft even if lock is broken
• Bearings extend and remain in shaft inhibiting lock removal
• Square key design virtually eliminates lock picking
