Abstract: An overhead tracked door selfsealing device suitable for easy retrofit of existing door installations which have no self sealing feature. It is comprised of a bracket and a spring driven cam system that is attached to the door track at the roller shaft points when the door is in the closed position. As a result, a lateral force imparted by the cam against the roller shaft via the pre-loaded spring forces the door against the jamb.
