Hardroom door edge seal
View Patent ↗A pair of fabric EMI gaskets run in parallel and adhered onto a perimeter of a conductive ferrous hardroom door surface. A row of magnets running in between the pair of fabric EMI gaskets is magnetically adhered onto the perimeter of the door surface. A series of conductive non-ferrous spring clips are inserted between the pair of fabric EMI gaskets in at least corners of conductive ferrous hardroom door surface. A strip of felted wool is deployed above the non-ferrous spring clips and the row of magnets. A cam lever rotatably attached between the hardroom door pries open and breaks magnetic forces between the row of magnets and a conductive ferrous surface of a door frame.
