The top of the obstacle is a storm collar secured, not secured, to the smokeshaft. Above the ceiling, the air and vapour obstacle is wrapped around the drywall to contact the firestop sealant.


A collar-like ceiling trim plate is connected below the firestop. Job securely around electric circuitry (shut off the power).
