Automatic Louvre Opener | Two Wests

This Automatic Louvre Opener can be fitted to our louvre kit & most other popular models.

Operates on the same principle as the Bayliss openers - i.e. a stainless steel cylinder containing a mineral wax which expands with heat, causing the vent to open, as the temperature falls the wax contracts & the opener closes.

Has a release catch to allow manual opening & closing.
