ABSTRACT:
A magnetic door sweep and magnetic threshold is disclosed which reliably aligns and seals to prevent water, air and pests from crossing the threshold of a door. Additionally, the magnetic door sweep and magnetic threshold will prevent shape loss of the door sweep. The magnetic door seal includes a primary seal and a door seal magnetic element having a first set of poles located on the bottom edge of a door. A magnetic threshold includes a threshold cap and a threshold magnetic element having a second set of poles. The door seal is positionable relative to the threshold as the door is closed such that the first set of poles is attracted to the second set of poles when said door seal is positioned proximate to the threshold allowing the primary seal to extend between the door and the threshold.
