The vial housing is constructed from Structo-Cast plastic, an impact-resistant material that keeps the tool light enough to minimize line sag during use. Unrestricted hooks allow the level to slide freely along the line without having to remove and reattach it at each measurement point. Designed for fast, repeatable leveling checks, the 575 is a standard hand tool for masons, landscapers, and sheet metal workers.\u003c\/p\u003e\n\u003cp\u003eThe 575 is suited for residential and commercial applications where a string line is used to establish grade or alignment. Common use cases include laying masonry courses, establishing landscape grades, and aligning sheet metal installations. The lightweight Structo-Cast body reduces the downward bow in the string that can introduce leveling error, making it a practical choice when the line must span longer distances between anchor points.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch impact-resistant level vial for clear, accurate readings\u003c\/li\u003e\n  \u003cli\u003eStructo-Cast plastic construction reduces weight and minimizes line sag\u003c\/li\u003e\n  \u003cli\u003eUnrestricted hooks allow free sliding movement along the string line\u003c\/li\u003e\n  \u003cli\u003eSuitable for masonry, landscape grading, and sheet metal work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard string line level for use in masonry, landscaping, and sheet metal applications where a lightweight, hook-mounted vial level is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHook the 575 onto a taut string line at or near the midpoint between two anchor points for best accuracy. Ensure the string line is properly tensioned before reading the vial, as excessive sag will produce an inaccurate level reference. No tools are required for attachment or removal. Store the level away from impact hazards to preserve vial integrity over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVial Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction Material\u003c\/strong\u003e: Structo-Cast plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.048 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: 00049448575008\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: JOHNSON LEVEL TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 575\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JOHNSON LEVEL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51347382796594,"sku":"575","price":23.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549418.jpg?v=1782103270","url":"https:\/\/voomisupply.com\/products\/johnson-level-tool-575-line-level-3-inches-structo-cast","provider":"Voomi Supply","version":"1.0","type":"link"}
