Dave, Don't have the new rack dims handy but I can give you the basic tub dims.....
The original racks I built were made with openings of 6.25" x 20.25" x 40" so I believe the actual tub dims to be 6 1/8" x 19 3/4" x 38 1/2"
Floor area is 16 3/4" x 35 1/2" = 4.13 square feet
My racks are ten high and just under 6' tall overall
It is my new standard for male caging. Way back when I had a different wood cage I housed a single pair in. When I decided to start breeding I built the first of my wood breeder cages 2' x 2' x 19" 8 sections. Then a few years later decided to expand and built a second one for a total of 16 spaces. After that I got some boaphile cages and shortly later looked into tubs and a rack to house animals not actually being bred. I found the CB110 tub to have the most floor space of what I could find without going into an overly high tub. I built two racks 10 high out of hoe improvement store grade melamine. Worked ok but when seriously messy, the melamine would swell and make the tubs a little hard to pull. Next expansion was to go from two to four racks, decided to have them made out of plastic and sold off the two older melamine ones. LOVE the Animal Plastics version of CB110 racks!!
Now I house all females to be bred in the wood cages with a few overflowing into the Boaphiles and two kinda cool cages I picked up in a cage collection I bought. The concept is stackable units, the bottom being 4 old rubermaid brand tub racks, the middle being a shorter tub on bottom with glass door cage on top with a PVC pass-through between. The top being only 6 inches and is for the controls. I have two of these and will be trying them out this year, only for the middle section cage/tub combo. I think it will work well for a single breeding pair. Eventually the lower tubs will house some of my current babies.
Other not to be bred this year and most of my males are in one of my BRB room CB110 tub racks. Notable exception is Fluffy, he gets a boaphile cage section, I like to see him more. Just about to put the second CB110 rack into service to house my growing up subadults.
