ABSTRACT:
A novel locking clip is disclosed for use with either fire or smoke dampers, which locking clip normally does not interfere with the operation of those dampers but, which under activation conditions, allows the blades of the damper to move into the desired position, but effectively prevents the blades from moving out of that position until fire conditions have passed.
