Product Description

The Grandio Automatic Louver Window Opener opens and closes a Grandio wall louver window with the temperature, with no electricity. A heat-sensitive wax cylinder pushes the louver open as the greenhouse warms, and a return spring closes it as it cools.

Key features

  • No wiring or batteries – runs entirely on greenhouse heat.
  • Gradual response – no sudden drafts or temperature swings.
  • Left-side mount – fits the left side of current Grandio louver windows.
