The kit uses an aluminum extrusion with a vinyl insert that compresses against the door surface to block air infiltration, dust, water intrusion, and insects. Installation requires no drilling or screw holes. Instead, the seal attaches using a factory-applied 3M adhesive backing. The aluminum face delivers a flat, clean finish that suits painted or natural metal door frames. This seal is sold as a complete kit with enough material for one standard door.\u003c\/p\u003e\n\u003cp\u003eThis product is suited for residential and light commercial entry door applications where door jambs have an existing slot profile or a clean flat surface for adhesive bonding. It is commonly installed during weatherization service calls, door replacement projects, or seasonal maintenance routines. Installers working on exterior entry doors will find the peel-and-stick process straightforward. The kit includes five 42-inch pieces and one vinyl connector, covering the full perimeter of a standard door frame in a single installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum extrusion with vinyl insert creates a compressible airtight seal against air, dust, water, and insects\u003c\/li\u003e\n  \u003cli\u003e3M adhesive backing eliminates the need for screws or drill holes\u003c\/li\u003e\n  \u003cli\u003eFits slotted door jambs and flat jamb surfaces\u003c\/li\u003e\n  \u003cli\u003eKit includes five 42-inch pieces and one vinyl connector for a complete single-door installation\u003c\/li\u003e\n  \u003cli\u003eFlat metal surface finish suits painted and unpainted aluminum frames\u003c\/li\u003e\n  \u003cli\u003eBrown finish blends with common door frame colors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement weatherstrip seal for standard residential entry doors with slotted or flat door jambs.

Before installation, clean the jamb surface thoroughly to remove dust, grease, and old adhesive residue so the 3M backing bonds properly. Measure and trim each piece to fit before removing the adhesive liner. Avoid installing on surfaces below the minimum application temperature specified on the adhesive packaging, as cold temperatures can reduce initial bond strength.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum with vinyl insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiece Length\u003c\/strong\u003e: 42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces Included\u003c\/strong\u003e: 5 jamb pieces plus 1 vinyl connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoverage\u003c\/strong\u003e: Top and sides of one standard door\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Method\u003c\/strong\u003e: 3M pressure-sensitive adhesive, no screw holes required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.742 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00043374433050\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: 43305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M-D BUILDING PRODUCTS","offers":[{"title":"Default Title","offer_id":51343525314866,"sku":"43305","price":41.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549584.jpg?v=1782022379","url":"https:\/\/voomisupply.com\/products\/m-d-building-products-43305-door-jamb-weatherstrip-seal","provider":"Voomi Supply","version":"1.0","type":"link"}
