1.Can the trailer coupler lock be easily removed by thieves?
The trailer coupler firmly connects the main vehicle and the trailer, which is inseparable from the safety protection of the lock. The MK663 lock beam is adjustable in height, with a range of 52~100mm, which is more susceptible to user preference. Users can adjust the lock beam height to minimize the gap between the ball cover and the lock, and tightly lock the coupler to prevent it from being easily removed by thieves.
