Measuring 3\/4 inch wide and 50 feet in length, this 21-gauge plain-finish steel strapping provides the structural support needed to prevent duct runs from sagging over long spans. HVAC technicians and mechanical contractors rely on this type of hanger strapping as a fundamental material in duct support systems where maintaining proper slope and alignment is critical to system performance.\u003c\/p\u003e\n\u003cp\u003eThis strapping is suited for use in a wide range of duct support applications, including insulated flexible duct, round pipe, and rectangular sheet metal duct. It is a standard go-to material for new construction and retrofit mechanical work where continuous hanger strap is needed to fabricate custom-length supports. The 50-foot coil allows technicians to cut lengths to suit the specific hanger spacing and drop required by the installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePerforated design allows for easy fastening at any point along the strap length\u003c\/li\u003e\n  \u003cli\u003e21-gauge carbon steel construction provides rigid support across long duct runs\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch width suits standard hanger hardware and fastener heads\u003c\/li\u003e\n  \u003cli\u003ePlain finish compatible with typical mechanical room and attic environments\u003c\/li\u003e\n  \u003cli\u003e50-foot coil length reduces splicing needs on extended runs\u003c\/li\u003e\n  \u003cli\u003eCompatible with flexible duct, round pipe, and rectangular duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with insulated flexible duct, round pipe, and rectangular duct as a support and hanger strapping material in HVAC duct systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDuct hanger strapping is typically installed by licensed HVAC technicians or sheet metal workers in accordance with SMACNA duct support guidelines and applicable local mechanical codes. Power down the air handling system before working in plenum or duct spaces. Use appropriate tin snips or aviation shears to cut strapping to length, and secure with sheet metal screws or hanger hardware rated for the duct weight being supported. Avoid sharp bends in the strapping that could reduce load capacity at the support point.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Perforated Hanger Strap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 21 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Flexible Duct, Round Pipe, Rectangular Duct\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: WARWICK HANGER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3500-50\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WARWICK HANGER","offers":[{"title":"Default Title","offer_id":51468575703346,"sku":"3500-50","price":19.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946822.jpg?v=1783918011","url":"https:\/\/voomisupply.com\/products\/warwick-hanger-3500-50-perforated-band-strapping-21-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
