ABSTRACT:
A resilient and compressible door channel magnet module facilitates the installation of a door channel magnet. The module comprises a magnet set supported inside a magnet holder that is connected to a flexible and deformable outer ring by a set of elongate web members. To install, the module is compressed, positioned in the door channel, and released. The pressure of the module against the walls of the door channel retains the module in position. A preferred module includes a rare earth magnet backed with a ceramic magnet for producing the requisite magnetic field strength at less cost than a sole rare earth magnet of equal magnetic field strength.
