M-d Building Products 71548 Caulking Cord Weatherstrip

Product Description

The M-D BUILDING PRODUCTS 71548 is a flexible, self-adhesive caulking cord weatherstrip designed to seal gaps around doors and windows in residential and light commercial applications. The cord measures 90 feet in length, 3/16 inches wide, and 1/8 inches thick, giving installers enough material to cover multiple openings in a single roll. The white finish blends with standard interior trim. Because no tools are required, this weatherstrip is well-suited for quick service calls or maintenance work where minimizing labor time matters. It blocks drafts, dust, and moisture on both interior and exterior surfaces and can also be pressed into cracked window pane joints as a temporary or supplemental seal.

This caulking cord is appropriate for residential doors, windows, and frames where a compressible, adhesive-backed seal is needed. It works on interior and exterior installations, handling common infiltration points such as door frames, sliding window channels, and single-pane window perimeters. It is a practical stock item for weatherization contractors, property maintenance technicians, and general contractors performing envelope sealing work. The self-adhesive backing allows direct application to clean, dry surfaces without mechanical fasteners or additional adhesives.

Installation Notes

Installation is performed by general contractors, weatherization technicians, or maintenance professionals. Before applying, clean the mounting surface thoroughly and allow it to dry completely to ensure proper adhesion. No tools are required, but a utility knife or scissors may be used to cut the cord to length. Work in ambient temperatures that allow the adhesive to bond effectively, and avoid stretching the cord during application to maintain a consistent seal profile.
