Abstract
A chimney cap and a method for making the same are described. The chimney cap is more consistently and uniformly manufactured, which permits nesting.

The substantially square or rectangular cage is stretched to form a shaped trapezoidal cage, with a top portion of each side of the cage having a longer span that a bottom of portion of each side.
