The diffuser is formed form a cylindrical pipe which is flattened on most of its length but left partially cylindrical for convenient mounting. The mounting arrangement includes a removable saddle on the air lateral and a Tee fitting for mounting the diffusers. The saddle has an outlet spout which fits directly against and is connected directly to an inlet leg of the Tee fitting. The saddle construction in one form accommodates either standard U.S. or metric pipe fittings and in another form accommodates two different sizes of pipe fittings.Other References
