Abstract

A mounting fixture secures a duct to a generally channel-shaped support section having right angle flanges at the distal ends of its sidewalls. The duct mounting fixture includes a base plate having an outer side defining a bearing plane against which an endwall of a duct is adapted to bear. A well or bush receiving a preferably rotatable latch member is located in a middle zone of the base plate. The latch member is adapted to extend through an opening in the endwall of the duct and grip the endwall. At least two retaining teeth are disposed on the underside of said base plate for cooperation with the right angle flanges of a support section and at least one of the retaining teeth is carried by a resiliently deformable arm. The latch member is contiguous with base plate and permanently held along the axis of the well or bush.
