Abstract
A unitary extruded weatherstrip for doors and the like including a flexible loop having a floating bulb therewithin connected to the wall of the loop and functioning as a secondary seal. The floating bulb under compression, prevents collapse of the loop inward or outward to provide an effective seal. The failure of the weaterstrip outwardly to collapse prevents its protrusion past the face of the door whereby to retain the aesthetic appearance of the installation. The same weatherstrip configuration can be employed on both the hinge and the lockside portions of the frame as well as along the header thereof. A rigid depending portion flange can be provided as a part of the weatherstrip extrusion to permit installation into the saw-kerf of wood door frames, for example, without requiring special tools.
