Looking good! CLIMB Adelita, CLIMB!
I got this for the snakes to climb on. It's not too heavy for me, but heavy duty enough for even a full grown BI for sure. It also folds up really thin and has wheels.

I can also use it to stand on when I clean the top tanks, although I usually just use a step stool.
The one criticism I have is the "shelf" piece has two holes in it, a small one and a bigger one. I watch the snakes when they climb, but they could conceivably get stuck. I plan to remove that piece ASAP.
