Yep! They sure do! You can go to http://www.visionproducts.us/htm7/racks.html and they have racks ready to go. You will need a thermostat. However, they use heat cable, not tape. Just to let you know.
there a lot of companies out there that sell fully setup racks that you assemble at home. Some use heat rope, some use tape, there are a ton of options out there.
Often they are more expensive than building them yourself, but much less stress and labor.
I agree with Mel and Keith, I use Reptile Basics Racks. I use the the 'Narrow' versions of the Iris STC-410 rack system for all of my breeders. I also have a set up for hatchlings, I have 4 of the 16 Iris shoe box racks from them as well.
The service is amazing, I ordered my rack, they installed the heat tape, and shipped it out to California from North Carolina... the ENTIRE process from ordering to delivery at my door only took 7 DAYS!
and the best thing is... is is fully assembled and shipping is included! My geckos love em!
