I thought Boaphiles were seam welded and didn't have any glue involved.
That said, I haven't seen a Boaphile cage meant for retics.
Mathew Martin makes cages. I believe Monster Cages is still in business.
Honestly, a display cage for a really big retic, needs more than the typical cage manufacturing company. IF,,,, display is your goal.
This is probably a very expensive option. http://www.jworlds.net
That said, if you have one retic and display is your goal, I'd look into it.
