M-d Building Products 63628 Epdm Weatherstrip D Profile

Product Description

The M-D BUILDING PRODUCTS 63628 is a D-profile EPDM cellular rubber weatherstrip designed to seal large gaps around doors and windows. Made from 100% EPDM (Ethylene Propylene Diene Monomer), it blocks drafts, dust, and moisture from entering the building envelope. Each roll covers approximately 17 feet and features a factory-applied self-adhesive backing for fast, tool-free installation. The material stays flexible across a wide temperature range, from -40 degrees F to 140 degrees F, making it suitable for use in both cold-climate and hot-climate applications. The D-profile cross-section is specifically shaped to compress against door frames and window sashes where gap widths are on the larger side.

This weatherstrip is intended for residential and light commercial use on exterior doors and windows. A single roll provides enough material to seal one standard door or two average-size windows. Installers, general contractors, and maintenance technicians use this product during new construction, renovation, and routine building envelope maintenance. It is particularly well-suited for retrofit applications where existing seals have cracked, compressed, or lost their flexibility over time.

Key Features

• D-profile design sized for large gaps around doors and window frames
• 100% EPDM cellular rubber construction for long-term durability and weather resistance
• Remains flexible from -40 degrees F to 140 degrees F
• Self-adhesive backing eliminates need for fasteners or adhesive primers on most surfaces

Compatibility

Designed as an OEM-style replacement or new-installation weatherstrip for standard residential and light commercial door frames and window sashes requiring a D-profile seal for larger gap widths.

Installation Notes

Installation is typically performed by a general contractor, maintenance technician, or experienced DIYer and requires no specialized tools. Clean and dry the bonding surface thoroughly before applying the self-adhesive backing to ensure a lasting bond. Do not stretch the strip during application, as this can cause it to pull away from the surface after installation. Confirm the gap size is appropriate for the D-profile before installation to achieve proper compression and an effective seal.
