Abstract
A dishwasher spray arm having a top wall portion joined to a bottom wall portion. The wall portions are constructed to be formed from identical Z-shaped sheet blanks. The wall portion edges define securing structure which, while being different in the two wall portions, are each preselected to closely fit within the Z-shaped sheet blank configuration. The Z-shaped blanks define a continuing series arranged to be cut from a strip of sheet material with a common edge between successive blanks, effectively minimizing material wastage in the formation of the spray arm. In the illustrated embodiment, the top wall portion defines further structure differing from that of the lower wall portion.
