Actual dimensions of a 4x4 floppy?

[Hectorxd]

I am building a grip van right now and plan on getting some floppies but I don't have them yet. I am building out a box for them beside a shelf and need the actual dimensions of a Matthews 48x48 floppy including the support arm. Any help would be great.

Have you tried their website yet? Or B&H? B&H is a quick way to look up specs like weight and dimensions of gear.

B&H and Matthews site says 48x48. They don't provide total length with the support arm which is what I am concerned with.
