It features a rectangular head with a dial graduated in 1-degree increments across a 0 to 180 degree range. The 6-inch blade provides a stable reference surface for measuring angles on workpieces, fixtures, and assemblies. At 0.25 pounds, it is lightweight enough for bench use or field work. Licensed tradespeople, machinists, pipefitters, and HVAC installers rely on this type of instrument when accurate angle layout or verification is required during fabrication or installation work.\u003c\/p\u003e\u003cp\u003eThe 50672 is suited for layout, inspection, and angle-setting tasks in residential and commercial trade work. The rectangular head style seats securely against flat reference surfaces, making it practical for ductwork layout, conduit bending verification, pipe angle checks, and general fabrication measurement. The 1-degree dial graduation gives sufficient resolution for most trade applications where angular accuracy matters without requiring a more complex digital or vernier instrument.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-inch blade length for stable contact on workpieces and reference surfaces\u003c\/li\u003e\n\u003cli\u003eDial graduated at 1-degree increments for direct-read angular measurement\u003c\/li\u003e\n\u003cli\u003eFull 0 to 180 degree dial range covers most layout and inspection angles\u003c\/li\u003e\n\u003cli\u003eRectangular head design seats flush against flat surfaces for repeatable readings\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.25 pounds for easy one-handed use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose dial protractor suitable for trade layout, fabrication inspection, and angular measurement tasks across HVAC, plumbing, electrical, and mechanical applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this instrument. Before taking measurements, ensure the reference surface and blade are clean and free of debris that could affect seating accuracy. Handle the dial face carefully to avoid impact damage that can affect calibration. Periodic calibration checks against a known reference angle are recommended to maintain measurement accuracy in production or inspection environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 1 degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Range\u003c\/strong\u003e: 0 to 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 50672\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542506570034,"sku":"50672","price":141.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18e1ebb96033c84294c8a4ce5fba9158.jpg?v=1785902311","url":"https:\/\/voomisupply.com\/products\/starrett-50672-dial-protractor-6-in-blade-rectangular-head","provider":"Voomi Supply","version":"1.0","type":"link"}
