M-d Building Products 87981 Door Jamb Weatherstrip 36x84 in

Product Description

The M-D BUILDING PRODUCTS 87981 is a compression-style door jamb weatherstrip designed for residential entry doors. It installs directly onto the doorstop or serves as a full doorstop replacement. The unit combines straight-grained wood and synthetic composite construction with an integrated foam and vinyl seal that blocks air infiltration, moisture, and drafts. At 36 inches wide by 84 inches tall, it fits standard single-door frames. Pre-primed wood accepts paint for a finished appearance. Fasteners are included. Licensed contractors and experienced DIYers handle installation as part of door weatherization and energy-efficiency upgrades.

This weatherstrip is intended for residential exterior door applications. It works on standard 36-inch door frames with a 7-foot height and is suited for wood-frame construction where the doorstop and weather seal are combined into a single component. The pre-primed finish allows field painting to match existing trim. Typical installation occurs during new door unit setup or as a replacement when existing doorstop weatherstripping has failed, compressed permanently, or been damaged.

Installation Notes

Installation is typically performed by a finish carpenter, general contractor, or qualified DIYer. Power down any electric door hardware and ensure the door is closed and stable before removing existing doorstop or weatherstrip material. Fasten the jamb weatherstrip securely using the included fasteners, checking that the foam and vinyl seal compresses evenly against the door face. Follow local building codes for weatherization requirements on exterior door assemblies.
