It features 112 trapezoidal teeth spaced along a 420L belt profile with a pitch length of 420.00 mm. The belt body is constructed from nylon with a fiberglass tension cord, combining flexibility with dimensional stability under load. Licensed mechanical trades and equipment technicians install this belt in timing-critical drive systems where slip cannot be tolerated and synchronous motion between shafts must be maintained.\u003c\/p\u003e\n\u003cp\u003eThis timing belt is suited for use in light industrial machinery, HVAC equipment drives, conveyor systems, and other synchronous drive applications that specify the L-series trapezoidal tooth profile. The 420L designation identifies the belt section and pitch length, making it a direct reference for specification-based replacement. It is appropriate for both OEM assembly and field replacement work where exact tooth count and belt section must match the existing drive design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eL-series trapezoidal tooth profile for positive, no-slip power transmission\u003c\/li\u003e\n  \u003cli\u003e112 teeth with a 420L belt number and 420.00 mm pitch length\u003c\/li\u003e\n  \u003cli\u003eNylon belt construction resists wear and maintains tooth geometry under cycling loads\u003c\/li\u003e\n  \u003cli\u003eFiberglass tension cord provides high tensile strength with low stretch\u003c\/li\u003e\n  \u003cli\u003eSingle-piece continuous loop design for clean installation without fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for synchronous drive systems that specify an L-series timing belt with the 420L belt number and 112-tooth count.

De-energize and lock out all drive equipment before removing or installing the belt. Do not force the belt onto pulleys using a screwdriver or pry tool, as this can damage the tension cord. Confirm correct tension per the equipment manufacturer's drive specification before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Number\u003c\/strong\u003e: 420L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Section\u003c\/strong\u003e: L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 112\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Shape\u003c\/strong\u003e: Trapezoidal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Length\u003c\/strong\u003e: 420.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Internal Length\u003c\/strong\u003e: 42.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCord Material\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: L Series Belts Positive Drive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CONTINENTAL CONTITECH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20043121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTINENTAL","offers":[{"title":"Default Title","offer_id":51557934104882,"sku":"20043121","price":43.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7ad939ff596e5721a84d7fe3720a31f.jpg?v=1786398803","url":"https:\/\/voomisupply.com\/products\/continental-contitech-20043121-timing-belt-420l-112-teeth","provider":"Voomi Supply","version":"1.0","type":"link"}
