Q-Matz For MES 30" How Much Do I need?

[smesh]

Anyone know how big the racks are in a MES 30"?  I have one arriving on Friday and want to order a Maverick 733 and some Q-Matz material for the smoker from Amaze-n but since the hasn't arrived smoker yet, I can't measure the racks. Can anyone provide that info so I know what to order?

Thanks.

I went ahead and order 2' of 24" so I think I'm good.  Got black.  Don't know what the difference is, but w/e. :) Thanks.
