The leaf measures 0.029 inches thick, 0.5 inches wide, and 12 inches long, with consistent thickness along the full length thanks to its parallel leaf design. Constructed from high carbon steel, it delivers the rigidity and wear resistance required for repeated use in shop and field environments. HVAC technicians, machinists, and service mechanics use feeler gages like this one to verify valve clearances, burner orifice gaps, and component tolerances during installation and maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis feeler gage is suited for residential and light commercial service applications where precise clearance measurement is required. Typical use cases include checking heat exchanger gaps, blower wheel clearances, electrode spark gaps on ignition assemblies, and general mechanical fitment verification. Its 12-inch parallel leaf provides consistent contact across longer measurement surfaces, making it reliable for flat and planar gap checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.029-inch thickness for precise gap and clearance measurement\u003c\/li\u003e\n  \u003cli\u003eParallel leaf design ensures uniform thickness along the full 12-inch length\u003c\/li\u003e\n  \u003cli\u003eHigh carbon steel construction provides durability and resistance to bending\u003c\/li\u003e\n  \u003cli\u003e0.5-inch leaf width offers stable surface contact during measurement\u003c\/li\u003e\n  \u003cli\u003e12-inch length accommodates extended reach in tight or deep assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-leaf feeler gage suitable for general mechanical and HVAC service applications requiring 0.029-inch gap measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFeeler gages are hand tools requiring no power source or fasteners. Insert the leaf into the gap being measured with light, consistent hand pressure to check fit. Do not force the leaf into a gap or use it as a pry tool, as this can deform the leaf and compromise measurement accuracy. Clean the leaf after each use to prevent corrosion and maintain accurate readings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.029 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Length\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0433 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: 91-382-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699125715250,"sku":"91-382-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6289913d91aee31033e587b53cba65f8.jpg?v=1788372505","url":"https:\/\/voomisupply.com\/products\/spi-91-382-2-feeler-gage-0-029-in-parallel-leaf-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
