M-d Building Products 63669 Epdm Rubber Weatherstrip 10 Ft

Product Description

The M-D BUILDING PRODUCTS 63669 is a self-adhesive EPDM cellular rubber weatherstrip designed to seal extra-large gaps around doors and windows. Constructed from 100% EPDM (Ethylene Propylene Diene Monomer) cellular rubber, this strip blocks drafts, dust, and moisture at the top and latch side of a door or around one average-size window. The 10-foot length and 19/32-inch profile make it suited for wider gap applications where standard weatherstrip falls short. Rated flexible from -40 degrees F to 140 degrees F, it holds up across extreme seasonal temperature swings without cracking or taking a set.

This weatherstrip is intended for residential and light commercial door and window sealing applications. It is appropriate for exterior entry doors, interior climate-control doors, and single windows where air infiltration, dust intrusion, or moisture seepage is a concern. The self-adhesive backing allows installation without mechanical fasteners, making it accessible for both trade professionals performing weatherization work and knowledgeable property owners managing their own maintenance.

Installation Notes

Surface preparation is critical for adhesive-backed weatherstrip — clean and dry the mounting surface thoroughly before application, removing old adhesive, paint flakes, or debris. Power tools are not required; a utility knife and tape measure are the primary tools. Apply firm, even pressure along the full length of the strip to ensure adhesive contact. In cold-weather installations, allow the adhesive to reach full bond strength before subjecting the seal to heavy use.
