Testing has demonstrated that many doors fail at the top corner due to improper contact with the weatherstrip. Air pressure can cause water to flow over the top of a door and down the interior column of the weatherstrip, creating air and water infiltration.

The Simple Corner works with the door's existing compression weatherstrip blocking water and air infiltration at the upper corners of a door unit.

• Works with existing weatherstrip
• Enhances door unit performance up to 25%
• Easy to install, visually non-intrusive

Constructed of a long-life foam, the Simple Corner is easily installed behind the weatherstrip to keep the area sealed when subjected to high pressure.
