M-d Building Products 43848 Rubber Weatherstrip 17 Ft Brown

Product Description

The M-D BUILDING PRODUCTS 43848 is a 17-foot rubber weatherstrip designed to seal gaps around doors and windows against drafts, dust, and air infiltration. The strip uses a silicone and EPDM rubber blend that stays flexible and resilient across a wide temperature range, from -40 degrees F to 140 degrees F. Its wave profile conforms to irregular gap surfaces for consistent contact. This weatherstrip is sold in brown and is appropriate for both residential and light commercial installations performed by general contractors, carpenters, or knowledgeable property maintenance technicians.

This weatherstrip is suited for exterior and interior door frames and window perimeters where air sealing and draft control are required. The 17-foot length provides enough material to seal a standard door opening with strip to spare, or to cover multiple window applications in a single roll. The wave profile design is particularly effective at maintaining contact pressure across uneven frame surfaces. Available in brown to blend with common wood and painted frame finishes.

Key Features

• Silicone and EPDM rubber blend resists cracking and compression set over time
• Rated for temperatures from -40 degrees F to 140 degrees F for year-round performance
• Wave profile design maintains consistent seal across uneven door and window frames
• 17-foot length covers a standard door perimeter with material remaining
• Brown color finish for compatibility with common frame finishes

Compatibility

Designed as a general-purpose replacement or new-installation weatherstrip for residential and light commercial door and window frames where a wave-profile rubber seal is appropriate.

Installation Notes

Installation is typically performed by carpenters, general contractors, or experienced property maintenance staff and requires no specialized trade license. Clean and dry the frame surface thoroughly before applying the strip to ensure proper adhesion. Cut the strip to length with scissors or a utility knife, and test-fit before final installation. No power tools or specialty equipment are required for standard door and window applications.
