as the combination of cl 30 and cl 60 u2032 or alternately as also shown in fig2 that the outlet portion 60 can be adjusted anywhere over 180 degrees of rotation so that the centerline thereof may vary anywhere between cl 60 and cl 60 u2032 wherein the inlet portion 30 and the outlet portion 60 are adjustably alignable along parallel but offset longitudinal axes for conventional construction in the united states i have found that it is convenient to provide the dryer vent adapter in a nominal overall diameter d of eight 8 inches equal to approximately 2 times r 14 inside diameter as indicated in fig2 and as will be understood by those of ordinary skill in the art and to whom this disclosure is directed in such cases the inlet portion 30 is normally provided with a nominal overall diameter of four 4 inches also it is customary to provide an outlet portion 60 of equivalent diameter to the inlet or of four 4 inches in diameter my novel dryer vent adapter 9 as described herein utilizes first 10 and second 12 cylindrical portions that are freely rotatable before assembly with 360 degrees of freedom so that the inlet 30 and outlet 60 portions are adjustable between a a first position wherein the inlet portion 30 and outlet portion 60 are oriented along a common longitudinal axis and b a second position where the inlet portion 30 and said outlet portion 60 are oriented along parallel but offset longitudinal axes in one commonly utilized configuration where the overall diameter of the first 10 and second 12 cylindrical portions are of a nominal eight 8 inches in diameter where the inlet portion 30 and said outlet portion 60 are each provided in a nominal four.
