Door Bottm Thresholds

Heavy guage aluminum channel holds a flexible silicone sweep that extends the length of the door bottom. The sweep is half-bulb shaped, designed to press against a threshold to form a weathertight seal along the bottom of the door. (Aluminum is non-corroding and will withstand all kinds of weather conditions for many years. The silicone sweep will remain flexible even at low temperatures and resists wear and tear.)
