Pemko Q102D Encased Foam Kerf-In Weatherstrip — Dark Brown, 5/8 In. Reach, 97 In. Length

The Pemko Q102D is a kerf-in encased foam weatherstrip designed to create a durable, compressive seal along door perimeters. Also referenced as a kerf-in bulb weatherstrip, this single 97-inch piece installs directly into a saw-kerf channel routed into the door stop, allowing the encased foam bulb to compress against the door face and close gaps that allow air infiltration, moisture, dust, and sound passage. With a 5/8-inch reach and a total installed height (kerf included) of 1 inch, the Q102D is engineered for a clean, low-profile fit in standard kerf-stop applications. Finished in Dark Brown, it blends discreetly with stained wood door frames and stop moldings.

Institutional Grade Features & Benefits

• Encased Foam Bulb Seal: The foam core is fully encased within a resilient outer jacket, providing consistent compression across the full door perimeter while protecting the foam from wear and tearing during repeated door cycles.
• Kerf-In Installation: Slides into a standard saw-kerf cut in the door stop — no adhesives, exposed fasteners, or surface-applied hardware required. This delivers a clean, factory-finished appearance on both new construction and retrofit applications.
• 5/8-Inch Reach: The bulb extends 5/8 inch from the kerf spine, accommodating typical gaps between door stop and door face and ensuring positive contact and sealing pressure.
• 97-Inch Single-Piece Length: Ships as one continuous 97-inch strip, sufficient for a full door height on most standard commercial and residential door openings, minimizing seams and potential leak points.
• 1-Inch Total Height with Kerf: The combined spine-and-bulb profile measures 1 inch in total height, ensuring compatibility with kerf depths and stop profiles dimensioned to this standard.
• Dark Brown Finish: Coordinates with wood-tone frames, stained oak, mahogany, and similar dark door stop finishes for a refined, unobtrusive appearance.
• Air, Moisture & Dust Control: When properly installed, the compressed foam bulb forms a continuous perimeter barrier that helps reduce drafts, water infiltration around door edges, and particulate entry — supporting building envelope performance.
• Retrofit & Replacement Ready: Ideal as a direct replacement for worn, cracked, or compressed-out kerf-in weatherstripping on existing door stops without requiring frame modification beyond a standard kerf slot.
