What Is a Door Sweep?

Quick answer

The strip along the door's bottom edge that closes the gap over the threshold.

The strip of rubber or bristle attached along the bottom inside face of an exterior door to close the gap above the threshold. Screw-on aluminum sweeps with slotted height adjustment outlast stick-on ones, and the blade should just touch the threshold. A dragging sweep tears itself off within a month.
