THRESHOLDS
The purpose of a threshold is to close the gap between the bottom of a door and the floor. Thresholds are used with door bottoms and weatherstripping to seal the opening, preventing air, rain, and snow from entering. Dunbarton has four standard styles with two extenders for the fixed inswing, with other options available.
