{"product_id":"vessa-louvered-vent-cover-4-6-inch","title":"Vessa Louvered Vent Cover — 4\" \u0026 6\", Gravity Damper with Screen","description":"\u003cp\u003eThe vent cap is the last thing on a duct run and the first thing weather finds — and Vessa's louvered vent cover is built to hold that line. Three gravity-hinged damper flaps swing open on the exhaust stream and fall shut the moment the dryer or fan stops, sealing off the cold air, rain, and snow that a fixed grille invites straight back down the duct. Behind them sits a metal mesh screen, so the same opening that vents your laundry doesn't become a nesting cavity for birds, mice, or wasps in the wall. The ABS body won't rust, streak, or bleed corrosion down the siding the way a painted-steel cap eventually does, and four corner screw holes with the screws included mean a swap-out takes minutes with a driver. Available in 4-inch and 6-inch to match the two most common vent sizes, it's the quiet part of the run that decides whether the duct stays a duct — or turns into an open door.\u003c\/p\u003e","brand":"NorthLine Signature","offers":[{"title":"4\"","offer_id":42990121648222,"sku":"VENTCAP4","price":15.99,"currency_code":"CAD","in_stock":true},{"title":"6\"","offer_id":42990121680990,"sku":"VENTCAP6","price":20.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0605\/0073\/8142\/files\/Gemini_Generated_Image_va2jlava2jlava2j.png?v=1783639530","url":"https:\/\/gdbuildingsupply.com\/products\/vessa-louvered-vent-cover-4-6-inch","provider":"Good Day Building Supply Inc.","version":"1.0","type":"link"}
