Kingpin Lock

Your trailer door may be locked, but could a tractor still back up and drive off with the whole thing? Not with a kingpin lock. This lock attaches directly to your trailer’s kingpin, preventing any unauthorized tractor from coupling to it and towing it away. Easy to install, made from rugged steel for long-term reliability, it’s effective enough to prevent theft. Tip: hang a flag or colored string about 90 cm from the lock to signal to drivers that the trailer is protected. Combine it with a gladhand-style lock for optimal protection.
