Disconnect power to electric dryers or shut off the gas supply to gas dryers before disconnecting or reconnecting exhaust ducting. Keep the transition duct run as straight and short as possible to maintain proper airflow and reduce lint accumulation. Do not use sheet metal screws that protrude into the duct interior, as they collect lint and create a fire hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Quick connect collars\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: UL2158A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 per case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LAMBRO INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 322ULC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51524635066674,"sku":"322ULC","price":145.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84d20d4baa7af8cd147ddd142e98f3d2.jpg?v=1785453621","url":"https:\/\/voomisupply.com\/products\/lambro-industries-322ulc-rigiflex-dryer-duct-4in-x-2ft","provider":"Voomi Supply","version":"1.0","type":"link"}
