Question about support

I had a 2nd level for mine too, and what I had done was just put a cube in the center on the bottom of the 2nd level to hold it up. However that takes away some room and I've read that you can use some kind of PVC pipe or piece of wood to give it support as well. You just have to be sure its in place and steady. The other thing is take a cube and bend it (which is easy to do) into a circle and use that. They all work.


Also, besides the connectors, the cable ties or zipties help tremendously in keeping the cage together.

When I had a second tier on my 4X5 I went and bought some long wood trim from the store and placed it on the grids and this allowed the second level to sit on it. You can see it here:

As you can see the wood runs across the cage and the grids hold them in place. It worked nicely the whole time I used a second tier.
