Measuring 5.25 inches wide by 4.5 inches high, this lens filters intense arc light and radiant energy during MIG, TIG, and stick welding operations. At 0.264 pounds, the lens is lightweight and sized for standard welding headgear filter frames. It meets ANSI Z87.1 requirements for optical and impact performance, making it a code-compliant replacement for fixed-shade filter applications in industrial and trade settings.\u003c\/p\u003e\u003cp\u003eThis lens is suited for professional welders, fabricators, and maintenance technicians working in industrial plants, construction sites, and fabrication shops. A fixed shade lens is the standard choice in applications where arc characteristics are consistent and the operator does not require variable shade adjustment. Shade 11 is typically specified for medium- to high-amperage arc welding processes. The 5.25-inch by 4.5-inch format fits welding helmet filter frames designed to accept this standard passive lens size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFixed Shade 11 filter for consistent arc light protection during medium- to high-amperage welding\u003c\/li\u003e\n\u003cli\u003eDimensions of 5.25 inches wide by 4.5 inches high suit standard passive lens filter frames\u003c\/li\u003e\n\u003cli\u003eMeets ANSI Z87.1 for optical quality and impact resistance\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.264 pounds minimizes added helmet weight\u003c\/li\u003e\n\u003cli\u003ePassive fixed-shade design requires no batteries or electronic components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fixed shade welding lens for helmets and goggle frames accepting a 5.25-inch by 4.5-inch passive filter plate with a Shade 11 rating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of replacement welding lenses is typically performed by the welder or a safety equipment technician without specialized tools. The lens slides or snaps into the filter frame of the welding helmet according to the helmet manufacturer's instructions. Inspect the lens for cracks or scratches before each use, as a damaged lens must be replaced immediately. Lens replacement and eye protection standards in industrial environments are governed by ANSI Z87.1 and applicable OSHA 29 CFR 1910.133 requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Shade\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.264 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI Z87.1\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: PRO-SAFE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4x5SF11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SAFE","offers":[{"title":"Default Title","offer_id":51728522281266,"sku":"4x5SF11","price":16.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26ec2abffae66d82fd9210114b895827.jpg?v=1788692658","url":"https:\/\/voomisupply.com\/products\/pro-safe-4x5sf11-fixed-shade-welding-lens-shade-11","provider":"Voomi Supply","version":"1.0","type":"link"}
