Pipe, No Interior Trim Plate, 3440","description":"\u003cp\u003eThe Lambro 4-in. aluminum exhaust hood vent with 11-in. pipe is for venting through the wall. It features an opening and closing damper that prevents outside elements and air from entering the vent. The damper seals the vent opening when the clothes dryer or bath fan are not running because no exhaust air exits the vent. When the appliance operates, the exhaust air pressure pushes the damper open to let the exhaust air escape from the vent. The exhaust vent is for new and replacement installations over an existing 4-in. opening. It features an opening with a net-free area of 20.5 sq. in., allowing for less back pressure. The vent’s manufacturing material is 26-gauge aluminum for durability and will not rust to maintain longevity. Make sure to check local building codes before installation.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRecommended for clothes dryer or bath fan exhaust installations\u003c\/li\u003e\n\u003cli\u003eFor new or replacement vent installations\u003c\/li\u003e\n\u003cli\u003eMounts over existing 4-inch openings\u003c\/li\u003e\n\u003cli\u003e11-inch pipe for through-the-wall installation; does not include interior trim plate\u003c\/li\u003e\n\u003cli\u003eDesigned for maximum airflow\u003c\/li\u003e\n\u003cli\u003eFeatures an opening with a net-free area of 20.5 sq. in.\u003c\/li\u003e\n\u003cli\u003eOpening and closing damper stays closed when not in use\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMade of 26-gauge aluminum hood for durability and will not rust to maintain longevity\u003c\/li\u003e\n\u003cli\u003eInstallation screws not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Lambro","offers":[{"title":"Default Title","offer_id":53347544629555,"sku":"3P2059-LAO3440","price":18.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/8051\/1795\/files\/LAO3440.jpg?v=1778846820","url":"https:\/\/verdi.com\/products\/lambro-4-in-aluminum-wall-exhaust-hood-vent-with-damper-and-11-in-pipe-no-interior-trim-plate-3440","provider":"Verdi","version":"1.0","type":"link"}
