You can fit up to TWO units per cold frame - one at each end.
The frame is manufactured from high quality plain aluminium alloy - the louvre vent is ONLY available plain (not coloured).
The louvre is glazed as standard with acrylic.
Available as a Manuel Louvre Vent or Automatic Louvre Vent - the automatic version includes an oil filled automatic opener which automatically opens and closes with temperature changes.
Please note this Louvre Vent can only be fitted to the Access Value Cold Frames and should be ordered at the same time that you order your Access Cold Frame.
