Roof Curbs and Accessories

Grainger has a selection of roof curb adapters that allow you to use an existing roof curb and help save installation time when replacing a fan or ventilator. They're available in a number of sizes to fit your specific application. Ventilated roof curbs are designed to ventilate hot exhaust ducts in commercial kitchen applications, and to protect the building and roof members. Metal bird screens help prevent birds from flying into your exhaust fans and roof vents, and can also protect fans from small objects and debris.
