The Curb Mount Base is designed for curb mount installations. Generally a 2" x 4" or 2" x 6" curb box is built and flashing is attached to the perimeter of the curb box. Curb mount installations should be used on flat or very low slope roofs. Curb mount installations are also recommended for higher profile roofs, such as ceramic or concrete tile, certain metal roofs, thick wood shake, etc. The flashing materials are generally metal, but can be made of certain types of roofing materials. Care should be taken to isolate dissimilar metals and to properly waterproof the curb box to the roof.
