M-D 80630 U-Shaped Door Bottom w/Drip Cap 36'' L X 1-3/8'' W x 1-1/4'' Bronze Enhance your home?s energy efficiency and weather resistance with the M-D 80630 DB002 Series Door Bottom with Drip Cap, a durable, bronze-finished aluminum threshold seal designed to create a tight, weatherproof barrier at the base of exterior doors. Measuring 36 inches in length, this U-shaped door bottom is engineered for use with standard 1-3/4-inch thick doors and provides a secure, long-lasting seal that helps block drafts, rain, dust, and pests. Constructed from high-quality aluminum with a corrosion-resistant bronze finish, this door bottom withstands exposure to moisture, UV rays, and temperature extremes without rusting, warping, or fading. The integrated drip cap extends outward to direct water away from the door?s edge and threshold, preventing water intrusion, rot, and structural damage?especially important for entryways exposed to wind-driven rain. This feature makes it ideal for front doors, back patios, and side entries where weather protection is critical. The rigid U-channel design slips over the bottom edge of the door and is secured with included screws for a strong, no-gap installation. It is not self-adhesive, ensuring a permanent, vibration-resistant hold that won?t loosen over time. The 1-3/8-inch width and 1-1/4-inch height provide full coverage across the door bottom, while the internal vinyl seal compresses when the door closes, creating an airtight and watertight barrier. This significantly reduces energy loss, helping to maintain indoor temperatures and lower heating and cooling costs. Designed for easy installation, the M-D 80630 requires only basic tools and can be installed in minutes. It works in conjunction with a smooth top threshold to form a complete weatherseal system, minimizing air infiltration and improving overall door performance. The sleek bronze finish blends well with most door hardware and trim, offering a clean, professional appearance.
