Abstract: A magnetic weather strip for sealing a door within a frame comprises a pre-bent thin iron based resilient metal strip of L shape extending along the sides and top edge of the door and secured thereto. A wood strip is mounted upon the frame along the sides and top of the door and has a compressible resilient filler mounted along its length and interlocked therewith. An elongated magnetic strip is embedded within the filler opposed to the metal strip, with the filler in yieldable sealing engagement with the metal strip when the door is closed, and the metal strip attracted to the magnetic strip.
