ABSTRACT:
Sealing apparatus for overhead doors in which a horizontally disposed elastomeric reservoir containing a quantity of fluid is secured to a header above the door and spaced tubular elastomeric members are secured at each side of the door to the building structure. The tubular members are in fluid communications with the fluid in the reservoir. An elongated flat bar secured to the top of the door bears against the reservoir when the door is closed causing fluid to be forced into the tubular members, extending them into sealing contact with the side edges of the door, while the reservoir seals the edges along the top of the door. Opening of the door releases the fluid pressure permitting the tubular members to retract and return fluid to the reservoir.
