A flat piece of metal. The "I" referred to the shape, not the cross
section. It is held in by the two side screws of the module plus the
two side screws of the adjacent module. To replace a module you'd
need to take out 8 screws but the adjacent modules would stay in
place since they still had 2 screws each on their other respective
sides.
Nothing behind the panel, nothing in-between to change the spacing,
simply a decorative piece of trim sandwiched between the screws and
the modules on the surface. I put a drawing in the files section.
