Hey guys,
I used this guide to make my own enclosure. Worked out great! (Reference source Striking Serpents).

Thanks a bunch for this tutorial. I have made four of these so far for my boas and they work great. I do build them a bit different by putting the sides inside of the top and bottom for more support and I add plastic footing to them for the gap in the cage, but they work perfectly. I am going to be building at least four more.

to anyone who has used or designed these?

How are you preventing sagging over the long haul? 4 feet is a huge gap not to support.

The glass track/glass would prevent sagging, but if you wanted to go with swinging doors, just run a strip like on the bottom and put it on the top. It will give you enough support to prevent sagging.

Thanks for that, Toker. I'm thinking I'll try it, and add a glass door hinged at the top, that swings up from the bottom...maybe

Awesome... Definately gonna make a few of these
