Full Product Description
⚠️ Made to Order — October Batch
The Treehouse Switch XL is one of our highest-demand enclosures and sells out every time. This October batch is limited to 75 units, produced together in a single run. Estimated ship date: start of November or late October. Orders are fulfilled in the sequence they are received. Once these 75 are gone, the next batch date is not yet scheduled.
The One Enclosure Built for Large Arboreals
Large arboreal tarantulas have specific demands — height, front access to avoid destroying webbing, solid ventilation, and a secure closure that won't fail on a fast-moving old world species. The Tarantula Cribs Treehouse Switch XL was engineered around every one of those demands.
At 12"x12"x18", this is one of the largest purpose-built arboreal tarantula enclosures on the market. Combine it with a Canopy lid and you're looking at 24 inches of vertical space — enough for even the most ambitious Poecilotheria or Stromatopelma build.
Key Features
-
Front-Sliding Magnetic Door — Front-only access means you never blow out top-anchored webbing during feeding or maintenance. The magnetic seal keeps the door firmly shut between uses — no latches, no clips, no rattling.
-
Top-Opening Lid — Secondary access from the top for full enclosure access when you need it. Use it for deep setups, rehouses, or heavy maintenance.
-
Modular Lid System — The defining feature of the Switch lineup. Swap lids in seconds to change ventilation, humidity, and lighting compatibility as your setup evolves.
-
3mm Cross Ventilation — Optimized cross-ventilation with holes near both the top and bottom of the enclosure, creating natural airflow throughout the full 18" height.
-
Premium Acrylic Construction — Crystal-clear panels on all sides. Your animal is always visible, always on display.
-

Always use magnetic locks as a safety measure. Keep magnetic locks away from children — ingestion risk and pinch hazard.

Why Tarantula Cribs?
