Therma-Tru Doors 36 Therma-Tru Door Sweeps (Brown Bulb)

Give your exterior door the tight, weather-resistant seal it deserves with this premium replacement sweep. Engineered specifically for 1-3/4-inch-thick doors that use a drive-on sweep, it features precise 7/8-inch barb spacing that slides into the bottom channel on many popular brands—including Therma-Tru (Benchmark), Stanley, Masonite, Castlegate, Scotty, Acore, and Jeld-Wen. Trim the thermoplastic body with household scissors for a perfect custom fit on narrower doors. Unlike standard vinyl sweeps that crack in the cold, this high-grade thermoplastic stays flexible in sub-zero temperatures, resists tearing, and stands up to years of door traffic. A dual-bulb interior seal compresses against the threshold to block drafts, dust, light, and insects, while the exterior drip-guard fin redirects rainwater away from the door edge to help prevent rot and corrosion. The 1/2-inch sweep height (not including barbs) bridges gaps up to 1/2 inch, restoring energy efficiency and comfort in minutes. Whether you’re upgrading a well-used entryway or finishing a new install, this replacement sweep delivers the professional look and performance of the original—no special tools required. Simply slide it on with the bulbs facing indoors and the drip fin toward the outside, close the door, and enjoy a tighter, quieter seal.
