DS7B/25 Door Seal, 1 In. X 7 Ft., Thermoset Plastic

The Frost King DS7B/25 door seal is a precision-engineered weatherstripping strip designed for kerfed millwork doors. This brown gasket slides directly into the standard 1/8" × 11/32" kerf found on many interior and exterior doors, creating an effective barrier against drafts, dust, noise, and moisture. A properly sealed door reduces heat loss, improves energy efficiency, and helps lower heating and cooling costs year-round.

Whether you're weatherproofing a single door or sealing multiple openings, this 7-foot continuous length provides ample material for most installations. The thermoset plastic construction resists warping, cracking, and UV degradation, ensuring reliable performance in demanding environments. Brown coloring matches typical wood door tones for a clean, unobtrusive appearance that blends seamlessly with any interior or exterior setting.
