Any of you guys with the Apex II kit, I am interested in replacing the mesh in my kit (on the way) with some that is not so wide open (see thru). I don't know how the dimensions though so I know how much I will need. Alot of places sell it 9" x 48" (but I think it is more than the 9" high, plus I need a 1" excess on all sides). Thanks for your help.
