Door entryway system
摘要:
A door entryway system can include a door sweep capable of attachment to a bottom of a door panel. The system also includes a threshold assembly having a self-articulating threshold cap configured to be biased toward the door sweep and interact therewith to form a sealing barrier when the door panel is in a closed position.
