Hey Kevin, If you are talking about Specturmranch pens, I believe he said thay are 2x4 6 gauge wire panels. Thoes look like the ones at my work, that are used for lions, tigers and the bears. Very strong pannels!
I applaud this thread Every one has awesome pens!
Just a side question for Specturmranch,(hope you all dont mind) All thoes animals on your website, are thoes all yours?
