The leaf measures 0.002 inches thick, 0.5 inches wide, and 12 inches long with a parallel profile that delivers consistent thickness across the full length. Constructed from tempered steel, it resists flex and wear under repeated use. HVAC technicians, machinists, and mechanical contractors use feeler gages like this one to verify valve clearances, burner orifice gaps, bearing tolerances, and other tight-tolerance measurements during installation and service work.\u003c\/p\u003e\u003cp\u003eThis gage is suited for both shop and field use wherever a 0.002-inch gap measurement is required. Typical applications include checking flue collar clearances, heat exchanger component fits, blower wheel tolerances, and general mechanical clearance verification on residential and light commercial equipment. The 12-inch leaf length provides reach into confined spaces common in HVAC and mechanical service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParallel leaf profile ensures uniform 0.002-inch thickness along the full 12-inch length\u003c\/li\u003e\n\u003cli\u003eTempered steel construction provides durability and resistance to bending under normal use\u003c\/li\u003e\n\u003cli\u003e0.5-inch leaf width offers a stable measuring surface for consistent gap readings\u003c\/li\u003e\n\u003cli\u003e12-inch length allows reach into tight or deep assemblies\u003c\/li\u003e\n\u003cli\u003eSingle-leaf format simplifies use when only one specific gap thickness is needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose feeler gage for use across HVAC, plumbing, mechanical, and industrial service applications where a 0.002-inch gap measurement is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gages are hand tools installed by HVAC technicians, machinists, and mechanical contractors during equipment inspection or assembly. Power down and lock out any equipment before inserting the gage into a gap on a mechanical assembly. Do not force the leaf into a gap narrower than the leaf thickness, as this can cause permanent deformation. Clean the leaf after each use to prevent corrosion and maintain measurement accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.002 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: Tempered Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 52839\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541586379058,"sku":"52839","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/200d61823a9b9f7cc9c10572cb922445.jpg?v=1785879961","url":"https:\/\/voomisupply.com\/products\/starrett-52839-feeler-gage-0-002-in-parallel-leaf-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
