Claim 4:
5. A vertical panel door stacking system, comprising:
a door comprising a first panel and a second panel, wherein the first panel and the second panel each comprise end caps coupled to opposite ends thereof, wherein each one of the end caps comprises:
a body portion comprising a top end, a bottom end, a front side, a back side, an inner side, and an outer side;
a cam lever coupled to the top end, wherein the cam lever is to rotate around an axis to generate a lift force to lift and separate the first panel from the second panel, wherein the cam lever comprises:
a cam body portion, wherein a center of the cam body portion is coupled to the inner side of the body portion via a rotatable coupling;
a first cam wheel coupled to and positioned on a first side of the cam body portion and adjacent a first end of the cam body portion, wherein the first cam wheel extends beyond the inner side of the body portion; and
a second cam wheel coupled to and positioned on a second side of the cam body portion opposite the first side and adjacent a second end of the cam body portion, wherein the second cam wheel is located between the inner side and the outer side and extends beyond the back side of the body portion; and

a first track wheel, a second track wheel, and a third track wheel, wherein the first track wheel, the second track wheel, and the third track wheel are each coupled to the inner side;

vertical door guide portions that include ramps that cause the cam levers of the second panel to rotate and lift and separate the first panel from the second panel as the door is opening;
track couplings coupled to the vertical door guide portions; and
horizontal door guide portions each coupled to a respective one of the track couplings, wherein each of the horizontal door guide portions comprises a first track and a second track, wherein the track couplings guide the first panel towards the horizontal door guide portions via the first track wheels, the second track wheels, and the third track wheels of the end caps of the first panel while the door is opening.
