Vertex In-80

[Enigma]

I would really like to purchase a Vertex IN-80.

What is preventing me from proceeding with the purchase is the footprint. There are all sorts of crazy, and widely varied, dimensions being thrown around. I can't find any recent numbers (within the last year, or so).

The return in my sump (where the skimmer will go) is 13.5"x8.75" with a tiny smidgen of wiggle room . . . I only measured to the 1/4"). These are the interior dimensions.

Some of the older claims that I've read indicate that these things can be squeezed into an 8.5"x11" footprint (on an angle).

Can any one confirm whether or not I'll be able to fit the most recent version of this skimmer into my return?
