The unit combines an aluminum body with a flexible vinyl insert that compresses against the floor surface to block air infiltration, dust, water, and insects. At 36 inches in length, it arrives pre-trimmed for standard 36-inch residential or light-commercial doors. Installation relies on 3M adhesive backing, so no drill, screws, or pilot holes are required. It is suited for building maintenance professionals, door and window installers, and knowledgeable DIYers looking to restore weathertight performance on an existing door without removing the door from its hinges.\u003c\/p\u003e\n\u003cp\u003eThis door bottom seal is intended for residential and light-commercial exterior door applications where energy efficiency and weather resistance at the door base have degraded. It is applied directly to the bottom face of the door slab and is designed for smooth, flat door bottoms. The pre-trimmed 36-inch length fits standard single-door openings without additional cutting in most cases. Installers working on narrower doors can trim the strip to the required width using standard tin snips or a utility knife before adhering it in place.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum body with flexible vinyl insert provides durable compression seal at door base\u003c\/li\u003e\n  \u003cli\u003ePre-trimmed to 36 inches for standard door width — trim down for narrower openings\u003c\/li\u003e\n  \u003cli\u003e3M adhesive backing eliminates need for drills, screws, or pilot holes\u003c\/li\u003e\n  \u003cli\u003eBlocks air, dust, water, and insects at the door bottom gap\u003c\/li\u003e\n  \u003cli\u003eInstalls in under 5 minutes — measure, trim if needed, peel, and stick\u003c\/li\u003e\n  \u003cli\u003eWhite finish suits painted interior and exterior door faces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an adhesive-mount door bottom replacement for standard 36-inch residential and light-commercial door slabs with a smooth, flat bottom surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by building maintenance technicians, carpenters, or door hardware installers. Before applying, clean the door bottom surface thoroughly to remove dirt, grease, and old adhesive residue — the 3M bond requires a clean, dry substrate. If trimming to width, cut with tin snips or a sharp utility knife before removing the adhesive liner. No power tools are required; however, verify the door closes freely after installation to confirm the seal compresses without binding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Vinyl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive System\u003c\/strong\u003e: 3M adhesive backing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.534 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M-D BUILDING PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 43301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M-D BUILDING PRODUCTS","offers":[{"title":"Default Title","offer_id":51346992005426,"sku":"43301","price":22.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549572.jpg?v=1782095829","url":"https:\/\/voomisupply.com\/products\/m-d-building-products-43301-door-bottom-weatherstrip-36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
