Abstract: A threshold weatherstrip for an inswinging door which is characterized by a channel member of reinforced plastic material having a U-shaped cross section with the flanges thereof adapted to engage opposite faces of the door bottom and a resilient compressible means seated in the upwardly opening channel with screws or similar fasteners for adjustably attaching the assembly on the bottom edge of the door, the compressible means, in one form thereof, being a foam plastic strip which is compressed and fills the space between the top face of the channel web and the bottom edge of the door, and a sweep-forming strip member depending from the bottom face of the channel member for sweeping engagement wite the sill surface. In an alternative arrangement the compressible means takes the form of spaced coil spring members disposed between foam plastic blocks, the latter closing the openings at the ends of the channel member.
