3a59 Aluminum Door Threshold, 36 In L X 1-3/4 In W

The Frost King 3A59 door threshold is an aluminum component designed to seal the base of doorways, blocking drafts, air leaks, and moisture entry. Installed between the door frame and floor, it creates a weathertight barrier that improves energy efficiency and indoor comfort. Homeowners and contractors use door thresholds to reduce heating and cooling costs, eliminate uncomfortable drafts, and protect interiors from weather exposure.

This threshold solves common problems caused by gaps at the bottom of doors: energy loss, temperature fluctuations, and moisture infiltration. A tight seal at the door base helps maintain indoor comfort and reduces strain on climate control systems.

Features and Benefits

• Triple Seal Design: An angled, multi-leaf construction creates a tight, positive seal that effectively blocks drafts and moisture from entering through the door opening.
• Slotted Holes for Adjustment: Pre-drilled slotted holes allow easy repositioning during installation to achieve the perfect fit and seal for your specific doorway.
• Extruded Aluminum: Aluminum construction provides durability and resistance to the elements for long-lasting performance.
• Bright Silver Finish: The attractive finish complements most door styles and architectural settings.
• Easy Installation: Comes with screws included for straightforward screw-mounted installation.
