ABSTRACT:
Sealing structure for providing a seal between the perimeter of a door and a surrounding structure such as a door frame. The sealing structure is preferably formed as a tri-part extrudate and is particularly useful in providing a seal for a structure (e.g., a refrigerator, freezer, walk-in freezer, etc.) where it is desirable to obtain a hermetic and/or thermal seal.
