The M-D Building Products 02618 is a K-profile EPDM cellular rubber weatherstrip designed to seal small gaps around doors and windows. Made from 100% EPDM cellular rubber, it blocks drafts, dust, and moisture in residential and light commercial applications. The strip measures 0.125 inches thick by 0.375 inches wide by 17 feet long and remains flexible across a temperature range of -40 degrees F to 140 degrees F. A self-adhesive backing simplifies installation without additional fasteners. M-D Building Products backs this weatherstrip with a 10-year flexibility guarantee, making it a dependable choice for energy-sealing work.
This weatherstrip is suited for residential door and window applications where small gap sealing is required. One roll provides enough material to seal one standard door or approximately two average-size windows. The extreme-temperature rating makes it appropriate for installations in climates with wide seasonal temperature swings, including cold northern regions and hot southern markets. Installers working on weatherization, energy efficiency retrofits, or new construction trim-out will find this strip straightforward to apply on clean, dry surfaces.
Designed as an OEM-style replacement or new-install weatherstrip for residential door and window frames requiring a small-gap K-profile seal.
Installation is typically performed by contractors, weatherization specialists, or knowledgeable DIYers as no special trade license is required for weatherstrip application. Before applying, clean and dry the mounting surface thoroughly to ensure proper adhesion of the self-adhesive backing. Cut the strip to length with a utility knife or scissors and press firmly along the full run, paying close attention to corners. Avoid stretching the strip during application, as elongation can reduce the effective sealing profile.
