Professional transportation lock ODM/OEM manufacturers
A coupler lock is a lock that locks car and trailer.
The safety of the trailer depends largely on the firmness, confidentiality and firmness of the trailer lock.
We recommend MK663, which has the advantages of “three highs” and allows drivers to use it with confidence.
High lock body strength
The coupler lock is extremely strong and more resistant to violent destruction.
MK663 is made of selected high-quality steel, with high strength, not easy to deform or damage, and can effectively resist external impact and pressure.
In addition to sudden violent destruction, there are also long-term environmental factors that threaten the firmness of the lock.
The steel of the lock itself is corrosion-resistant, and the surface is sprayed with painting and zinc plating to further enhance the anti-rust function, effectively resist the intrusion of rain, fog, and moisture, and extend the service life. Reduce the impact of rust on the firmness of the lock body, especially the lock beam that is susceptible to erosion but plays a key role in locking.
High lock confidentiality
The trailer lock adopts a number of anti-theft technologies to prevent technical opening.
MK663 is equipped with high-security key system, which is stable and reliable; the lock hole has unique shape, which plays a certain anti-pry role; the key milling teeth are precise and not easy to copy. The overall confidentiality is high, which effectively prevents illegal unlocking.

From the appearance, the basket-like structure of MK663 locks or fixes the coupler through the combined force of a locking beam and fixing seat.
