Why Choose This Trailer Hitch Lock?


Important Fitment Notice
Please check your tow ball diameter before purchase — this lock is designed for 50 mm size only. If your tow ball is a different size (e.g., 48 mm or 45 mm), the lock may not align correctly, or the coupling may not close fully. One buyer noted: “The ball on this hitchlock is 48mm diameter. The hitch is designed for a 50mm tow ball.”
Ensure bolt sizes, coupling style and clearance allow for proper lock installation.
