The GSV series of Venting Curb Mount skylights make a great replacement or new construction skylight to work with your curbed installation. Out of reach skylights will require an eye adapter and a skylight pole to operate. A minimum 3/12 pitch is necessary for either the curb or the roof. Both the rough opening and outside curb dimension must be adhered to for proper fit. The curb, and flashing for the curb are not included, but a flashing kit is sold under the Accessories menu. GSVs are not intended for vertical installations. An electric motor with wall switch and rain sensor is available for on-site installation, as well as a remote control for the ultimate ease of operation.
