Ace 96 in. L X 4 in. D Silver Aluminum Dryer Vent Kit

"This dryer venting kit includes everything you need for a new dryer installation, or to replace an existing dryer transition duct. Kit includes 8 feet of 4 inch diameter semi-rigid duct, 2 clamps and elbow connectors. Elbows come pre-connected to the transition duct, for a quick and easy installation. The smooth walls of the elbow connectors help reduce lint build-up and improve efficiency by ensuring better air flow to the outside exhaust vent. All components are made from aluminum to deliver better heat resistance. Semi rigid duct is rated UL 2158A for dryer venting. "
