The pin provides a strong anchor point for duct liner, securing insulation firmly to the duct surface while allowing a smooth transition from the insulation face down into the quilting depression. At 1.5 inches in pin size with a 1-inch diameter washer and a pin diameter of 0.13 inches, this fastener is built for consistent, repeatable placement during duct assembly. Sheet metal workers and HVAC fabricators install these pins during new duct construction and liner retrofit work.\u003c\/p\u003e\u003cp\u003eThe 26232 is suited for residential and light commercial HVAC duct liner applications where insulation must be mechanically secured before adhesive sets or as the primary retention method. The sloped washer profile is specifically designed to avoid tearing or compressing the liner face unevenly, preserving insulation integrity across the duct interior. These pins are commonly driven through duct liner into the sheet metal substrate using a stud welder or pin spotter during ductwork fabrication in shops or on job sites.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSloped CTC-series washer profile provides smooth transition at the quilting depression, reducing liner damage\u003c\/li\u003e\n\u003cli\u003e1-inch washer diameter distributes holding force across the insulation face\u003c\/li\u003e\n\u003cli\u003ePin diameter of 0.13 inches and length of 1.365 inches suit standard duct liner thicknesses\u003c\/li\u003e\n\u003cli\u003eWasher thickness of 0.015 to 0.017 inches keeps the fastener profile low against the liner surface\u003c\/li\u003e\n\u003cli\u003eLow-cost per-unit design supports high-volume duct fabrication workflows\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style weld pin fastener for use with duct liner insulation in standard sheet metal HVAC ductwork fabrication applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThese pins are installed using a capacitor-discharge stud welder or dedicated pin spotter tool; hand-driving is not the intended installation method. Ensure the duct panel surface is clean and free of coatings at the weld point to achieve a solid mechanical bond. Follow applicable SMACNA duct construction standards for pin spacing and liner attachment requirements. Verify the welder settings are appropriate for the pin diameter before beginning production runs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CTC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Length\u003c\/strong\u003e: 1.365 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Thickness\u003c\/strong\u003e: 0.015 to 0.017 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DURO DYNE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 26232\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURO DYNE","offers":[{"title":"Default Title","offer_id":51267874488626,"sku":"26232","price":437.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912681.jpg?v=1780692963","url":"https:\/\/voomisupply.com\/products\/duro-dyne-26232-sloped-washer-weld-pin-1-1-2-inch-ctc","provider":"Voomi Supply","version":"1.0","type":"link"}
