steel cable for opening your barn door from the side of your trailer.
This options enables you to open your barn door while you are at the side of your vehicle. It means that the driver does not need to be at the tail end of the semi trailer to open the doors, which avoids load falling on the driver. Furthermore, this option is extremely suitable for unloading in locations with a deep, large dump pit. This option allows the driver to drive up to the buffer blocks and then simply open the doors using the cable.
