The leaf measures 0.06 millimeters (mm) in thickness, 0.5 inches wide, and 12 inches long, giving technicians a stable, full-length blade for consistent contact across a measured gap. Constructed from high-carbon steel, the leaf resists wear and holds its calibrated thickness under repeated use. This type of gage is a standard hand tool carried by HVAC technicians, machinists, millwrights, and mechanics for checking clearances on burner electrodes, valve seats, spark gaps, and mechanical fits.\u003c\/p\u003e\n\u003cp\u003eParallel feeler gages like the 91-393-9 are used across residential and commercial service applications wherever a precise gap specification must be verified or set. Common uses include burner electrode gap setting on gas furnaces and boilers, igniter clearance checks, and general mechanical clearance measurement during equipment installation or preventive maintenance. The 12-inch leaf length accommodates deep-reach applications where a short blade would not make reliable contact.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.06 mm calibrated leaf thickness for precise gap measurement\u003c\/li\u003e\n  \u003cli\u003eParallel leaf style provides uniform thickness along the full 12-inch length\u003c\/li\u003e\n  \u003cli\u003eHigh-carbon steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.5-inch leaf width offers a stable contact surface\u003c\/li\u003e\n  \u003cli\u003eSingle-leaf format for straightforward go\/no-go gap checks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose parallel feeler gage suitable for gap measurement tasks in HVAC, mechanical, and industrial service applications where a 0.06 mm leaf thickness is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFeeler gages are used by HVAC technicians, mechanics, and millwrights as a measurement tool, not a permanently installed component. Before checking any gap on energized equipment, follow applicable lockout and tagout procedures. Insert the leaf with light, consistent pressure and avoid bending or forcing the blade, as this can alter the calibrated thickness over time. Clean the leaf after each use to prevent corrosion that could affect measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Thickness\u003c\/strong\u003e: 0.06 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\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\u003eMaterial\u003c\/strong\u003e: High-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111617\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: 91-393-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721541746994,"sku":"91-393-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bf68885f28ef74ad26244fd992a35e3.jpg?v=1788578681","url":"https:\/\/voomisupply.com\/products\/spi-91-393-9-feeler-gage-0-06mm-parallel-leaf","provider":"Voomi Supply","version":"1.0","type":"link"}
