The telescopic pipe element can be extended or reduced in length to suit the thickness of the wall and the ducting connection required.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEliminates the need for retropective core drilling\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e Telescopic pipe adjusts to suit wall thickness and ducting connection\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eLarger aperture and higher flow rate than single airbrick\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSuitable for extraction systems and underfloor ventilation\u003c\/li\u003e\n\u003cli\u003eGeometric Free Airflow 5\" pipe = 11,000mm²\u003c\/li\u003e\n\u003cli\u003eGeometric Free Airflow 4\" pipe = 7,300mm²\u003c\/li\u003e\n\u003cli\u003eVent measurements 219mm x 150mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Manthorpe","offers":[{"title":"Terracota \/ 4\"","offer_id":57546938843468,"sku":"BM06344","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Terracota \/ 5\"","offer_id":57547000316236,"sku":"BM06345","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Blue\/Black \/ 4\"","offer_id":57546938876236,"sku":"BM06346","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Blue\/Black \/ 5\"","offer_id":57547000349004,"sku":"BM06347","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Grey \/ 4\"","offer_id":57546938909004,"sku":"BM06348","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Grey \/ 5\"","offer_id":57547000381772,"sku":"BM06349","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ 4\"","offer_id":57546938941772,"sku":"BM06350","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ 5\"","offer_id":57547000414540,"sku":"BM06351","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Brown \/ 4\"","offer_id":57546938974540,"sku":"BM06352","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Brown \/ 5\"","offer_id":57547000447308,"sku":"BM06353","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Buff \/ 4\"","offer_id":57546939007308,"sku":"BM06354","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"Buff \/ 5\"","offer_id":57547000480076,"sku":"BM06355","price":40.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/manthorpe-terracota-4-thru-air-double-airbrick-1238515780.jpg?v=1778852809","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/thru-air-double-air-brick","provider":"Construction Supplies UK","version":"1.0","type":"link"}
