Diameter of S.F. reinforced parking meters?

Hi All

The city of San Francisco has reinforced their parking meter posts with
a second pipe over the existing pipe. The I.D. of the second pipe is
about the same as the O.D. of the original pipe, and is loose to turn
to prevent attacks with large pipe cutters. Does anyone know the O.D.
of this 2nd pipe? I want to buy a new Kryptonite Evo Mini lock, but I'm
not sure if it's large enough (at 3-1/2") to fit around the
reinforcement.

Any knowledge greatly appriecieated, John
