Side length of FN 142?

[jordanln97]

I'm getting a 142 soon (yay!) and I'm ordering ledges from Simply chintastic. I need to know the horizontal length of the side of the cage without doors. Also, is the Bass Equipment Ferret Pan 1 the pan that works with 142?

I believe if you just tell them you are getting it for the FN, they will know the size. They get alot of FN orders. I want to say it's between 22 and 24 inches though...
The Ferret pan #1 is the correct pan, the ferret pan #2 is the one with the cut out for the upper level.
