1" Stacking Spacer - for all Zen Habitats enclosure sizes (set of three)

A one-inch spacer set that sits between stacked enclosures. Stacking is how a single keeper becomes a multiple-enclosure keeper without needing a dedicated room — and the gap between units is what makes it work, giving airflow and a place for cables to run rather than being pinched between two frames.

• Airflow between units: two enclosures pressed flush trap heat between them. A gap lets the lower unit's warmth escape rather than loading the one above it.
• Somewhere for cables: thermostat probes, heat source leads and UVB cables need a route that isn't a pinch point.
• Fits the whole 3.0 range: one set works across enclosure sizes rather than being size-specific.
• Stack deliberately: heat rises, so the upper enclosure in a stack runs warmer. Verify each unit's gradient independently after stacking — don't assume the settings that worked standalone still hold.
