Additional deterrent to conventional anti-theft devices on the trailer coupling - especially for use whilst uncoupled.
Anti-theft device - The Safety-Ball stays in the coupling mechanism when the trailer is uncoupled.
Safety - Together with the Security Device the Safety-Ball protects against fast removal. A smaller towball or hook cannot be inserted into the coupling socket making the trailer more secure.
Open the coupling mechanism, insert the Safety-Ball and then lock the mechanism with your chosen security device.
