Key Features & Benefits
- Theft deterrent — locks over the 50mm tow ball coupling, preventing anyone from hitching the trailer to a vehicle without the key.
- Suits 50mm couplings — designed for standard Australian 50mm tow ball couplings including the ASTSS R1803A and R1809A.
- Keyed lock mechanism — solid lock barrel with keys for secure, convenient locking and unlocking.
- Visible deterrent — the presence of a coupling lock signals that the trailer is secured, discouraging opportunistic theft.
When to Use This Lock
Fit the R1103 coupling lock whenever your trailer is parked unattended — at home, on the street, at a boat ramp car park or at a worksite. While no lock is completely theft-proof, a coupling lock adds a significant barrier that deters casual theft and buys time for the owner to notice.
