ABSTRACT:
A dryer duct assembly employs two universal elbow components and at least one flexible component. The flexible component has ends capable of connecting to another flexible component or to a universal component without the use of other devices such as hose clamps to secure connection. Each elbow has ends capable of attaching either to the wall opening or the dryer, in addition to attaching to the flexible component in the same manner as the flexible components may attach to each other. The elbow has an outer portion resembling the outer portion of a quarter-toroid, and a square type inner portion. The outer portion is made of a pair of mirror image hemi portions connected at adjacent flanges. The inner portion has an L-shaped plate with flow-through orifices in each leg of the L.
