Features:

• Perfect Connector: This ducting is ideal for duct fan systems in air circulation and ventilation projects, helping move air efficiently and connect spaces with ease; Works with front- or top-loading dryers and fans; Duct connection specifications note: match duct size to fan diameter for a tight, leak-proof fit – e.g., pair a 4'' fan with 4'' ducting
