Abstract: A system for allowing a loading dock door to release from a track upon being struck by a fork lift or other sufficiently strong force. The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow the wheel assembly to move up the sidewall and out of the tracks, and a tensioned or spring loaded wheel assembly that allows the assembly to flex enough to ride up the sidewall and out of the tracks when the door is impacted.
