I stand corrected. The aforementioned D-rings are not visible in the
website photo.

This is not a fall arrest harness and the front D-ring is used for
positioning - not used for fall arrest. Here's what the Petzl rep said in an
earlier post:
>> " Although I am not exactly sure what "amateur radio tower climbing" is,
I can tell you that this harness is designed only for work positioning and
not fall arrest. Work requirements for fall arrest harnesses dictate that
these harnesses
be full body harnesses." >>
The problem is that if you were fall with a fall arrest lanyard
attached to the front D-ring, you would be caught with your body position
horizontally facing up which would cause probable damage to your spine. A
fall arrest harness has the fall arrest D-ring between your shoulder blades
which will catch you in a slumped over and more natural, safer position.
