The set includes a 4-inch steel blade graduated in 4R style, providing four graduation increments: 1\/64 inch, 1\/32 inch, 1\/16 inch, and 1\/8 inch. The square head is cast iron, delivering the durability and mass needed to hold a true 90-degree reference on the workbench. This tool is used by electricians, plumbers, pipefitters, HVAC technicians, and general trades professionals who require fast, accurate scribing and layout on metal, pipe, conduit, and framing stock.\u003c\/p\u003e\n\u003cp\u003eThe 56360 is suited for both residential and light commercial trade work where compact layout tools are needed. The 4-inch blade length makes it practical for tight workspaces and close-quarter layout tasks. Tradespeople who mark conduit bends, pipe cuts, or sheet metal cuts will find the short blade and solid cast iron head useful for controlled, repeatable measurements. The 4R graduation system is a recognized standard in precision layout, providing four distinct increment scales on a single blade face without the need to switch tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch steel blade with 4R graduation style for multi-scale reading\u003c\/li\u003e\n  \u003cli\u003eGraduation increments of 1\/64, 1\/32, 1\/16, and 1\/8 inch on a single blade\u003c\/li\u003e\n  \u003cli\u003eCast iron square head for stable 90-degree reference and resistance to wear\u003c\/li\u003e\n  \u003cli\u003e2-piece set includes blade and square head\u003c\/li\u003e\n  \u003cli\u003eCompact 4-inch format suited to close-quarter layout work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 2-piece combination square set compatible with typical trade layout and scribing applications across HVAC, plumbing, electrical, and general mechanical work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCombination squares require no installation but should be inspected for square accuracy before use by referencing a known flat surface. Keep the blade locking mechanism snug to prevent blade shift during measurement. Avoid dropping cast iron heads, as cast iron is brittle and impact damage can affect squareness. Wipe the blade and head clean after use to prevent rust on the steel blade.\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 4R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Increments\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: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.375 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111803\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: 56360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542752854322,"sku":"56360","price":141.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e338b71dad2a5a15153fa67a55c1206e.jpg?v=1785906266","url":"https:\/\/voomisupply.com\/products\/starrett-56360-combination-square-set-4-inches-2-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
