After safely reaching your destination, the last thing you need is for an accident to occur when you open your trailer. HERD’s Load Lock mounts directly to your trailer plate and prevents the door from fully opening in the event your cargo has toppled over in route to your destination. It can be set up with any Vanguard trailer in a few easy steps, and getting access to the inside of your trailer is as easy as flipping the latch mechanism. Protect yourself against unloading accidents, and stay on the road.
