A door that's 6.5 feet by 2.5 feet is 2,160 square inches, which amounts to just over 16,000 pounds of force.
But the lever moves approx 1m to pull the door back from its seating by 1cm, so there is a ratio of 100:1, i.e. only 160 pounds of force is needed on the lever to move it away from the seal...
