It accommodates roof pitches from 2.5\/12 to 9\/12, making it suitable for a wide range of sloped roof configurations without requiring a separate pitch-specific unit. The frame length spans 51-5\/8 inches down to 42 inches in adjusted position, and the unit ships at 3.55 pounds. Construction is aluminum throughout, with pivoting blades that redirect wind-driven rain and debris away from the attic opening. A licensed roofer or general contractor typically handles installation as part of attic ventilation work.\u003c\/p\u003e\u003cp\u003eThe 905W is used in residential attic ventilation applications where a single louver must serve varying roof pitches. The adjustable design is especially useful in production roofing or re-roofing projects where pitch varies across a housing tract or across sections of the same structure. The 8 inches x 8 inches perma-coated screen limits insect and debris intrusion at the vent opening. The 1-1\/2 inch wide mounting flange provides a secure bearing surface against the roof deck for flashing and fastening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable pitch range from 2.5\/12 to 9\/12 eliminates the need for pitch-specific louver SKUs\u003c\/li\u003e\n\u003cli\u003eFrame adjusts between 42 inches and 51-5\/8 inches in length to match pitch setting\u003c\/li\u003e\n\u003cli\u003eAluminum construction resists corrosion and UV degradation\u003c\/li\u003e\n\u003cli\u003ePivoting blades provide maximum weather protection against wind-driven rain\u003c\/li\u003e\n\u003cli\u003e8 inches x 8 inches perma-coated screen blocks insects and debris\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch wide mounting flange simplifies flashing and fastening to roof deck\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation louver vent for residential sloped roofs with pitches between 2.5\/12 and 9\/12.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed roofer or experienced contractor. Power or HVAC systems serving the attic space should be reviewed before cutting roof penetrations, and all flashing must be completed per local building code requirements. Fasteners should be driven through the mounting flange into solid roof decking, and sealant or roofing cement should be applied at flange edges per standard roofing practice. Do not install on roof pitches outside the rated 2.5\/12 to 9\/12 range, as blade alignment and weather protection will be compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Frame Length\u003c\/strong\u003e: 42 inches to 51-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoof Pitch Range\u003c\/strong\u003e: 2.5\/12 to 9\/12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScreen Size\u003c\/strong\u003e: 8 inches x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Flange Width\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LOMANCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 905W\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOMANCO","offers":[{"title":"Default Title","offer_id":51524825612594,"sku":"905W","price":76.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/782763da85f3ad5834cfe1d023262f4b.jpg?v=1785458731","url":"https:\/\/voomisupply.com\/products\/lomanco-905w-adjustable-louver-vent-8x8-inch-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
