Door & Window Weather Seal
The Frost King AC43H is a dark-grey vinyl weather seal designed for door and window openings. It measures 3.5 ft in length and is supplied new from Thermwell Products Co., Inc. The material resists moisture and remains flexible across seasonal temperature changes.
Suitable for standard gaps and DIY fitting
Homeowners sealing a single door or window will find the 3.5 ft roll convenient for one typical opening. Builders needing longer continuous runs or multiple openings should calculate total footage before ordering because this pack covers only a short span.
Performs steadily once installed
The vinyl strip maintains its shape and seal under repeated door cycles and outdoor exposure without hardening or tearing. It does not rely on adhesives that can degrade in heat, so the barrier stays effective through daily use and weather cycles.

Questions about this item
What width door or window frame does the 3.5 ft Frost King Weather Seal AC43H fit?
The seal is 3.5 ft long and can be trimmed to match the exact width of your door or window frame during installation.
Will the dark gray vinyl AC43H adhere to an older metal or wooden frame that already has adhesive residue?
Clean the frame thoroughly first; the vinyl seal bonds best to a dry, residue-free surface regardless of whether the frame is metal or wood.
How can I confirm the Frost King AC43H is sealing properly after I install it?
Close the door or window and check for light leaks or drafts along the entire 3.5 ft length; a continuous dark gray line with no gaps shows it is working.
