Dundas Jafine Exhaust Soffit Vent is designed to fit 4", 5", and 6" ducts, making it for bathroom and kitchen fan venting. This adjustable vent features a stylish flush mount design that can be painted to match the exterior color of your home, ensuring it blends seamlessly with your home's appearance. The outer grill and flap effectively prevent unwanted pests from entering your home, while the leakproof collar connection to the duct stops moist air backdrafts, maintaining your home's ventilation efficiency. Installation is straightforward with included instructions, a stencil template, and mounting screws. To install, you will need a drill with a driven attachment, a saw, a utility knife (for 5" duct connections), and a metal clamp matching the duct diameter. Model Number: SEVZW
