What Is a Reptile Rack?
A reptile rack is a stackable housing system consisting of a heated frame and a series of sliding tubs. Each tub functions as an individual enclosure — pulled out for feeding and cleaning, pushed back in to lock heat and humidity. Racks are the dominant housing system in professional breeding operations for one simple reason: they are efficient. A single rack can house 6–70+ animals in the footprint of a single large enclosure, with consistent heat provided by the rack’s thermostat-controlled heating system rather than individual heat sources per animal.
Racks are not display enclosures. The tubs are opaque, visibility is minimal, and aesthetics are not the point. The point is clean, consistent, scalable husbandry — and for that, nothing beats a rack.
Who Should Use a Rack
- Breeders and serious collectors with multiple animals of the same or similar species
- Keepers focused on husbandry efficiency over display aesthetics
- Anyone housing hatchlings or juveniles — small tubs are more appropriate than large enclosures for young animals
- Keepers who want consistent, thermostat-controlled heat across all animals without managing individual heat sources
Who Should NOT Use a Rack
- Display-focused keepers who want to observe their animals — use a PVC enclosure or glass terrarium instead
- Species that require height — arboreal species like green tree pythons or chameleons are not appropriate rack animals
- Keepers with only one or two animals — a single PVC enclosure is more practical and enriching for a pet animal
How Rack Heating Works
Most quality racks use an under-tub heat source — typically a heat tape or heat cable running beneath each row of tubs — controlled by a single proportional thermostat. The tub sits on the heat source, warming the floor of the enclosure and creating a belly heat gradient. The animal can move toward or away from the heat source by moving within the tub.
A proportional thermostat is essential. On/off thermostats produce temperature spikes; proportional thermostats modulate output continuously and hold a precise set point. The VE200 included with ReptiChip’s rack systems is a proportional thermostat — this is a meaningful spec, not a marketing detail.

Tub Size Guide
Tub size determines which animals and life stages a rack can house. Matching tub size to animal size is the most important purchasing decision.
| Tub Size | Best For | Species Examples |
|---|---|---|
| 8 Quart | Hatchlings, small juveniles | Ball python hatchlings, juvenile colubrids, leopard gecko hatchlings |
| 11 Quart | Juveniles, subadults, small adults | Juvenile ball pythons, adult leopard geckos, adult smaller colubrids |
| 23 Quart | Larger juveniles, adult colubrids | Subadult ball pythons, adult corn snakes, adult king snakes |
| 45 Quart | Adult large snakes | Adult ball pythons, adult boa constrictors, adult hognose snakes |
A common approach in ball python breeding operations is to use 8–11qt tubs for hatchlings and juveniles, then move animals into 23–45qt tubs as adults. Running two rack sizes covers the full life cycle of most commonly kept snake species.
Top Picks
1. ReptiChip VE-70 Rack with 45 Quart Tubs — Best for Adult Ball Pythons and Large Snakes
The VE-70 is ReptiChip’s large-format rack, built for adult snakes that need genuine floor space. The 45 quart tubs provide a substantial footprint suitable for adult ball pythons, adult corn snakes, and other similarly sized colubrids. Includes the VE200 proportional thermostat — the same thermostat used in ReptiChip’s professional incubator lineup. At $749.95, a single VE-70 houses a meaningful number of adult animals under consistent, thermostat-controlled heat — significantly more cost-efficient than individual PVC enclosures at that scale.
If you’re building a serious adult ball python collection and a rack system fits your husbandry approach, this is the ReptiChip configuration I’d look at first.

2. ReptiChip VE-6 Rack with 23 Quart Tubs — Best for Adult Colubrids and Subadult Ball Pythons
The VE-6 with 23 quart tubs is the mid-size option — large enough for adult corn snakes, king snakes, and hognose snakes, and appropriate for subadult ball pythons being grown out before moving to adult housing. Also includes the VE200 proportional thermostat. At $529.95, this is a practical entry point into rack keeping for keepers with a growing colubrid collection.

3. ReptiChip VE-6 Racks with 8qt and 11qt Tubs — Best for Hatchlings and Juveniles
The smaller VE-6 configurations (8qt at $569.95, 11qt at $529.95) are designed for hatchling and juvenile housing. If you’re producing clutches, a small-tub rack lets you house an entire season’s hatchlings efficiently in one unit. The 8qt tubs are appropriately sized for ball python hatchlings and small colubrids; the 11qt tubs give slightly more room for growing juveniles.

4. Animal Plastics Racks — Best Alternative Brand
Animal Plastics is the other major name in serious reptile rack systems. Their racks are built to a high standard and widely used by professional breeders. Lead times vary — AP often has a waitlist during peak season. Worth considering if ReptiChip’s sizing doesn’t match your needs exactly.

5. Freedom Breeder Racks — Best Modular System
Freedom Breeder offers a modular rack system with a wide range of tub sizes and configurations. Popular among keepers who want flexibility to mix tub sizes within a single rack system. Their CB70 and CB35 are well-regarded in the ball python community.

Rack vs. PVC Enclosure: Which Is Right for You?
| Rack System | PVC Enclosure | |
|---|---|---|
| Best for | Breeders, collectors, multiple animals | Pet keepers, display setups, single animals |
| Visibility | Minimal — opaque tubs | Front glass/acrylic panel |
| Heat system | Centralized, one thermostat for all tubs | Individual heat source per enclosure |
| Space efficiency | Excellent — stacked vertical footprint | One animal per enclosure footprint |
| Cost per animal | Low at scale | Higher per individual |
| Enrichment | Limited — tubs are minimalist | Full naturalistic setup possible |
Common Mistakes
Using an On/Off Thermostat
On/off thermostats produce temperature spikes that stress animals and can cause health problems over time. Always use a proportional thermostat with a rack system. The VE200 included with ReptiChip’s racks is a proportional unit — this is one of the reasons their racks are worth the price over cheaper alternatives.
Tubs Too Large for the Animal
Hatchlings and juveniles do better in smaller, more secure tubs. An adult-sized tub for a hatchling ball python can cause feeding and security issues. Match tub size to the animal’s current size and move up as it grows.
No Substrate or Minimal Substrate
Even in a rack tub, animals benefit from enough substrate to exhibit natural behavior. Paper towel works for quarantine and medical situations; otherwise provide a thin layer of appropriate substrate. Ball python hatchlings do well on paper towel initially, then transition to coconut chip or fiber as they grow.
Pairing Your Rack with the Right Substrate
Rack tubs work best with substrates that hold humidity without becoming waterlogged and are easy to spot-clean. ReptiChip and MicroChip are popular choices among ball python rack keepers specifically because the chip texture holds humidity well in the enclosed tub environment without matting or compacting the way pure fiber can.
