Frost King St26a Aluminum Door Threshold, 36 X 3 In., 3/4 In. Height

The Frost King ST26A is a low-profile aluminum door threshold designed to create a smooth transition between indoor flooring and exterior surfaces while sealing out drafts, moisture, and debris. Measuring 36 inches long, 3 inches wide, and standing just 3/4 inch high, this threshold combines durability with a refined appearance that suits most residential and light-commercial doorways. The slim profile minimizes tripping hazards and maintains a clean aesthetic without bulky appearance.

This threshold features a corrosion-resistant aluminum body topped with a flexible vinyl weatherseal insert that works together to block air leaks, water infiltration, temperature fluctuations, and pest entry. The low-profile rug design makes it ideal for high-traffic zones where a subtle transition is preferred, while the integrated seal protects both your home and flooring from the elements.
