ABSTRACT:
A shielding connecting structure is disclosed for permitting the opening closing of the electromagnetic seal of screening material as applied across a door and a door jamb wherein the screening material is attached to the jamb and applied along the door. A pair of compressible parallel oriented rubber hoses are mounted between the jamb and the material attached thereto and a single compressible rubber hose is mounted between the door frame and the material applied thereto. The hose on the door is arranged to be positioned between the two parallel hoses when the door is closed upon the jamb during which the hoses become compressed to produce a wiping contacting action between the associated portions of the material.
