Thermwell RV/DAT39 Threshold Vinyl Strip 36 Inches

Product Description

The THERMWELL RV/DAT39 is a replacement threshold vinyl strip designed to restore the sealing performance of an adjustable door threshold. This vinyl insert fits the Frost King DAT39H Adjustable Threshold and provides a fresh weatherseal surface at the base of an exterior door. At 36 inches in length, it replaces worn, cracked, or compressed vinyl that no longer creates an effective barrier against drafts, moisture, and dust. Installers and property maintenance professionals use this part as a cost-effective alternative to replacing the entire threshold assembly. It is sold in a package quantity of 12 units.

This vinyl strip is suited for residential and light commercial exterior door applications where a DAT39H adjustable aluminum threshold is already installed. It is a direct drop-in replacement that restores the threshold to full sealing function without requiring full door frame work. Typical installations include entry doors, back doors, and utility room thresholds subject to normal foot traffic wear.

Installation Notes

This vinyl strip is typically installed by general contractors, handymen, or experienced DIYers performing door weathersealing maintenance. No special tools are required beyond basic hand tools to remove and reinstall the threshold retaining screws. Close and latch the door before checking alignment of the new vinyl to confirm proper contact with the door bottom. Avoid stretching or compressing the vinyl during installation to maintain an even seal across the full door width.
