I have a similar situation to yours, but it's intentional.
My outdoor NEMA boxes have an aluminum plate that mounts to the back of the
box. But I wanted a bulkhead for mounting the suppressors so the cables
could enter one side, pass through the bulkhead and exit the other side.
(BTW, Polyphase does make flange-mount, but the bulkhead approach let's you
pack them in more densely.)
So I made the bulkhead out of aluminum and then mounted it at a right angle
to the back plate using some pieces of 1-inch aluminum angle from Home
Depot.
For the IS-RCT, I secured a small piece of 1-inch aluminum angle the main
plate. The bolt from the IS-RCT then goes through the angle and the IS-RCT
is essentially flat against the back plate. (It's not exactly flat because
the grounding bolt in the IS-RCT is at a small angle, but it works fine).
