Overall walk-around of nozzle extension handling fixture.

Picture 2 of 2.

The eight black pads around the periphery of the handling fixture are the nozzle exit strut pads, which actually support the nozzle extension; these sometimes leave darker rectangular areas in the interior of the nozzle extension.

The arms radiating from the top point of the fixture are nozzle flange struts which attach to the top of the nozzle extension to help hold the nozzle extension in place.

This photo dates from the summer of 2009; note the bare J-2 thrust chamber in the back left.
