The set includes a 6-inch steel blade and a forged steel square head. The blade is graduated in the 4R style, providing four graduation scales: 1\/64, 1\/32, 1\/16, and 1\/8 inch, giving the user fine-resolution readings across a single blade. The forged steel head delivers the rigidity needed for accurate 90-degree and 45-degree reference checks on material surfaces. This tool is a standard in the toolkit of electricians, pipefitters, HVAC technicians, and sheet metal workers who need reliable layout and squaring capability on the job.\u003c\/p\u003e\n\u003cp\u003eThe 56392 is suited for use in both residential and commercial trade applications where accurate marking, depth measurement, and squaring of materials are required. It works on metal, wood, and composite surfaces, making it practical across multiple trade disciplines. The compact 6-inch blade length is well suited for confined spaces and bench work common in mechanical and electrical rough-in tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-piece set includes a 6-inch steel blade and a forged steel square head\u003c\/li\u003e\n  \u003cli\u003e4R graduation style with four scales: 1\/64, 1\/32, 1\/16, and 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003eForged steel head provides durability and accurate 90-degree and 45-degree referencing\u003c\/li\u003e\n  \u003cli\u003eSteel blade resists flex for consistent layout readings\u003c\/li\u003e\n  \u003cli\u003eCompact 6-inch blade length suits confined-space and bench applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard combination square set for general trade layout and measurement tasks across HVAC, electrical, plumbing, and sheet metal applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand tool. Before use, verify the head locks securely to the blade with no perceptible play, as a loose head will produce inaccurate square references. Keep the blade clean and free of burrs to maintain graduation legibility and surface contact. Store the tool protected from impact to preserve the calibration of the head-to-blade fit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 4R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Scales (Inch)\u003c\/strong\u003e: 1\/64 inch, 1\/32 inch, 1\/16 inch, 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56392\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542061744434,"sku":"56392","price":185.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1dbc65c637d44a731e6ec2cac62d0310.jpg?v=1785890875","url":"https:\/\/voomisupply.com\/products\/starrett-56392-combination-square-set-6-in-2-piece-4r","provider":"Voomi Supply","version":"1.0","type":"link"}
