    Exhaust Vent

    Intake Vent

    Cover vents with caps that let air in or out.
    Exhaust Vent—A built-in damper allows air to escape while blocking backdrafts, rain, and snow.
    Intake Vent—Only fresh air enters though the screen—no debris or pests allowed.
    Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
    Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.

    Impact Driver Duct Crimpers

    Image of ProductInUse. Back orientation. Duct Crimpers. Impact Driver Duct Crimpers.
    Turn your impact driver into a power crimper, and create raised edges on sheet metal more quickly than with hand crimpers. Use on standard 30-24 ga. galvanized steel HVAC ductwork. They work with impact drivers in forward or reverse, so they are comfortable for both right- and left-handed users.
