Sold in a 45-foot roll and weighing 0.672 pounds, this gray cord applies by hand without tools or cartridge guns. Installers press it directly into gaps and seams where it conforms to irregular surfaces and holds without adhesives. Beyond window sealing, it functions as a gasketing material, sound deadener, insect barrier, crack filler, and general gap filler in residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThe F4 caulking cord is suited for residential weatherization work on single- and double-hung windows, casement windows, sliding doors, and similar framed openings. It is commonly applied during seasonal weatherproofing to reduce air infiltration. The gray color blends with standard window frames and sill finishes. Because it is removable and leaves minimal residue, it is also used in temporary or seasonal installations where a permanent sealant is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-foot roll provides sufficient coverage for multiple windows or door frames in a single package\u003c\/li\u003e\n  \u003cli\u003eHand-applied without caulking gun, cartridge, or special tools\u003c\/li\u003e\n  \u003cli\u003ePliable cord conforms to irregular gaps and uneven surfaces\u003c\/li\u003e\n  \u003cli\u003eFunctions as weatherstrip seal, gasketing material, sound deadener, and insect barrier\u003c\/li\u003e\n  \u003cli\u003eRemovable and repositionable — suitable for seasonal or temporary applications\u003c\/li\u003e\n  \u003cli\u003eGray color blends with standard window frame and sill finishes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose weatherstrip and caulking cord for use on residential windows, doors, and framed building openings where a hand-applied, removable gap sealant is appropriate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special trade license, but is commonly performed by weatherization contractors, general contractors, and knowledgeable property maintenance staff. Clean the surface of dust, oil, and loose material before applying the cord to improve adhesion and sealing performance. Press the cord firmly into the gap using fingertip pressure, working in continuous runs to avoid gaps in coverage. Do not paint over the cord, as this may affect removability and surface condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 45 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.672 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038092810948\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: MORTEX PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: F4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MORTEX PRODUCTS","offers":[{"title":"Default Title","offer_id":51346147770674,"sku":"F4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551586.jpg?v=1782072129","url":"https:\/\/voomisupply.com\/products\/mortex-products-f4-weatherstrip-caulking-cord-45-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
