The leaf measures 0.024 inches thick, 0.5 inches wide, and 12 inches long, giving technicians a full-length, rigid reference blade for checking valve clearances, burner orifice gaps, spark electrode spacing, and similar tight-tolerance fits. Constructed from high carbon steel, the blade resists wear and holds its dimension under repeated use. HVAC technicians, plumbers, and general mechanical trades rely on this gauge type when setting critical clearances during installation and service.\u003c\/p\u003e\n\u003cp\u003eThis feeler gauge is suited for residential and light commercial service work where precise gap measurement is required. Common applications include setting igniter-to-burner gaps on gas furnaces and boilers, checking clearances on compressor valve plates, verifying electrode spacing on oil-fired equipment, and general mechanical fitting work. The 12-inch parallel leaf length accommodates deep or awkward access points that shorter blades cannot reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeaf thickness: 0.024 inches for precise gap measurement at that tolerance\u003c\/li\u003e\n  \u003cli\u003eParallel leaf style provides consistent width along the full 12-inch length\u003c\/li\u003e\n  \u003cli\u003eHigh carbon steel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.5-inch width allows clearance checks in moderate-access spaces\u003c\/li\u003e\n  \u003cli\u003eSingle-blade format for fast, targeted use without sorting through a set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 0.024-inch feeler gauge blade suitable for mechanical, HVAC, plumbing, and electrical trade service applications requiring gap measurement at that thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed technician or qualified mechanic should verify equipment is de-energized and any gas supply is shut off before accessing components requiring gap measurement. Insert the blade with light, even pressure — forcing the blade can spring or distort it and compromise accuracy. Clean contact surfaces of oil and debris before measuring to ensure an accurate reading. Replace any blade that shows visible wear, bending, or corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.024 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.038 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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91-377-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690506387762,"sku":"91-377-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46153f8b8503c9691279918812905759.jpg?v=1788270732","url":"https:\/\/voomisupply.com\/products\/spi-91-377-2-feeler-gauge-0-024-in-parallel-leaf-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
