Circular Fire Dampers with Installation Frame
FDF

As above but includes a frame to enable installation in brickwork.

"Why would I need an installation frame?"
When exposed to high temperatures the steel casing of the damper will expand. In the absence of a frame, this would cause the mechanism to jam, preventing the damper from closing. The frame provides a cavity between the damper body and the brickwork. This allows for expansion and ensures the damper closes correctly.
