Abstract
The present disclosure is directed to a simulated roof vertical ventilation training apparatus configured to be pivotably attached to a simulated roof. In some examples, the vertical ventilation training apparatus includes a frame pivotably mounted to an exposed rafter of the simulated roof. The frame is moveable between an open position and a closed position. The edges of the frame are configured to engage with at least one disposable support member to maintain the frame in a closed position. The disposable support member is configured to be cut by a user with a hand tool to allow pivot of the frame into the open position.
