The Receiver Tube Disc is a small metal disc inserted into the bottom of the Receiver Tube on our Force 5K and 10K dollies. This piece is used to support and prevent friction between the Receiver Tube and the adapter while moving your trailer, providing the smoothest operation possible. The tube and disc are usually greased before shipping to ensure it’s all set for your use! To preserve this frictionless nature, we recommend reapplying grease annually.
