As a somewhat mature woman with the scantest of carpentry skills and a fear of using the hand held circular saw, my solution was to join two XL ReptiBreezes together, side by side. This should help.

One of the things that has helped was I used heavy duty garage shelving, which was the perfect length to hold them and keep them together. The hardest part was I had no helper, but none of my animals seemed to mind my occasional salty language.
