The brush seal mounts vertically along the sides of the door frame and creates a sweeping, weather-resistant barrier between the door and the body, helping to maintain interior temperature and keep out dirt, moisture, and debris. Over time, brush bristles can wear down or the vinyl retainer can crack, so you would replace this seal when you notice air leaks, visible damage, or compromised temperature control in the trailer.
