I have 6 Reptile Basics racks and 1 C Serpents rack. I’ll try to cover all the differences here. It should be noted that the Reptile Basics colubrid hatchling rack is an exception to many of the things I mention here, but is still an excellent quality rack.
The RB rack is made of thicker xpvc, which I’d imagine makes them less likely to warp over time. There’s a few nice touches like edges being rounded over. I probably wouldn’t mind the edges not being rounded over on the C Serpents rack if I hadn’t already been spoiled to the RB racks.
Both brands use flex watt style heat tape. The Reptile Basics rack has channels for the probe cord, and a slot that locks the probe into place. For the C Serpents rack you have to drill a hole in the back of the rack yourself, and tape the probe to the heat tape.
For the stacking system, the RB racks have 6 interlocking tabs to keep them in place. There’s 2 on each side running front to back, and 2 on the back running side to side. Since they are cut on a CNC, they always fit well.
The C Serpents rack uses dowels to hold multiple racks together. The dowels are inserted so close to the edge that they look like they would bust out through the side of the pvc pretty easily. The rack came with a note saying that “due to tolerances” the holes for pins in one rack may not line up with the holes in another rack.
The RB rack has a small hole in front of each tub to insert a small plastic pin. This is to keep snakes from pushing the tubs open. If you’re not worried about this happening, you simply don’t use the pins, and forget that the holes exist.
The C Serpent rack doesn’t have anything like this. I rigged up my own system using a long dowel and brackets made for holding electrical conduit.
The C Serpents rack came preassembled, as did my RB colubrid hatchling rack. The other RB racks came shipped flat, and I had to assemble them myself. It’s not a difficult processes. I’d say it’s less complicated to assemble than most lego sets.
With one order, FedEx crushed a box and broke several of the tubs inside. On another occasion, FedEx delivered my rack to some other address and refused to retrieve it. In both instances I contacted Reptile Basics, and they shipped replacements quickly without any hassle. I couldn’t be happier with their customer service. I haven’t had to contact C Serpents customer service, so I have no comparison there.
Overall I feel like Reptile Basics is better quality, and will last longer, and their customer service would be hard to beat. I’m sticking with RB until I make the switch to ARS in a few years hopefully.
One last note, you won’t really be able to see your snakes in either rack. While the C Serpents tubs are closer to clear than RB, they are not clear like glass. If the snake is at the very front of the tub, you will be able to see a colored blur. You’ll still have to open the tub if you really want to see them
