This kit combines our 312CR screw-applied gasket with sponge EPDM gasket, S44 adhesive-back style gasket, and our 2009APK acoustic threshold with integrated stop to provide optimal performance. The 2009APK threshold provides a continuous seal across the width of the opening and seals against the bottom rail and the face of the door to aid with dampening and absorption of sound waves.
