Here is a shot of the racks on one wall of my snake room...
From right to left....
Rack 1 is juvi colubrids that are almost ready to move up a bin size...
Rack 2 is juvi balls who are also almost ready to move up....
Rack 3 is adult and sub-adult colubrids. Some will stay in this size bin and some will eventually move up to the under-bed sized bins....
Rack 4 is adult and sub-adult balls...
The fridge is a colubrid egg incubator....
I have found my racks to be a great time and space saver. They are as heavy as all h3ll, but I don't plan to move them around too much.
I have a few more racks to build in the next couple months.
