Abstract
The air diffuser of this assembly has a top collar with a free edge and the damper is of conventional construction, having a central core and a set of radially outwardly extending strut arms. In the central core is mounted a vertical actuating screw for adjusting the air deflector blades of the damper. The outer ends of the strut arms are formed with a stop member resting over the top edge of the diffuser collar and with a system to deform the collar walls so as to lock the strut arms to the collar against axial movement and against rotation. The stops serve to locate the damper in its proper operative position so as to direct the air uniformly over the air diffuser baffles.
