Total Soccer Factory Total Soccer Factory Soccer Goal NETS (Regular and Junior Sizes) (6X12X3X6)

I need a 7'x5' foot net. Which size should I choose?

Is this a single net or a pair?

What are the measurements of the squares and would this net be strong enough to be used for disc golf discs?

My goal is 12’4” wide and 6’8” tall with a depth of 5’. Will this bet fit??
