This kit combines our 303AS screw-applied gasket with silicone bulb, S44 adhesive-back style gasket, and our 2006STC acoustic threshold with integrated stop to provide optimal performance. The 2006STC threshold provides a continuous seal across the width of the opening and seals against the face of the door to aid with dampening and absorption of sound waves.
