            Standard Threshold  Commercial Threshold Ideal for residential applications, the standard threshold is 4.5” wide and features a 1” exterior step (1.68” for inswing doors) that protects against water penetration and allows full perimeter weatherstripping on outswing doors, reducing air infiltration. Inswing doors are equipped with a weatherstrip assembly mounted to the bottom of the door that sweeps against the threshold. Finished to match the color of the frame. The Series 900 Hinged Door utilizes a low-profile commercial threshold that favors ease of entry over protection from the elements. Available in satin and bronze anodized finishes. Capable of meeting ADA (Americans with Disabilities Act) requirements. Note: The commercial threshold may be less effective at preventing water penetration than the standard threshold and therefore may not be appropriate in all climates, conditions, and exposures.
