Abstract

A fire damper in an air duct 2 is formed by a flap 12 which in its closed position bears on a flange 6 which extends inward from the duct wall, to form a seal. The flap 12 is biased to the closed position and held open by a cable 24 which is gripped by a releasable mechanism, such as a ball clutch. The release is triggered by a fusible cartridge 34 which extends into the duct 2.
