An alternate embodiment of the fin structure of the present invention provides for the manufacture of the fin structure in a substantially flat strip with coupling means on the opposite ends thereof for assembling the strip into a substantially cylindrical configuration at the time of installation on the filter element. Various forms of coupling means for engaging the opposite ends of the strip are also disclosed.
