The U-Shape Door Sweep is a wrap-around bottom seal designed to stop drafts, block insects, and prevent water intrusion at the base of your entry door. This sweep slides over the bottom edge of the door and creates a tight, continuous seal against the threshold—ideal for restoring energy efficiency and eliminating daylight gaps without removing the door from its hinges.
Engineered for 1-3/4" exterior doors, this U-shape profile provides a secure, uniform fit and is compatible with most standard steel and fiberglass entry doors. It is a reliable replacement for worn, cracked, or missing sweeps and installs in minutes with basic tools.
