Hi all,

At the bottom of exterior doors there's usually a piece of wood profiled
so as to direct the rain away from the door frame (normally has a groove
underneath so the drips can't find their way back inside under the door.
What's the name for this bit of wood, please?
TIA.

drip strip, weather strip.
