The Keder Domestic Autoroof vent is filled with wax and when it heats up it turns to liquid and expands, opening up the vent.

In storms, please isolate it by taking out the end pin and locking the vent

Available in 2m increments, the crop rails can be used in a single section or run the whole length or widtch of the greenhouse.  Ideal for hanging and stringing plants to.

For the 3m wide greenhouse the staging is 75cm deep, in the 2m greenhouse the staging is 50 cm deep.  Supported on a steel frame that comes off the main structure, it leaves the underneath completely free of obstructions

If you live in an area that experiences regular strong winds and high snow load, we would recommend purchasing the additional peace of mind gained from the Extreme Brace Kit

​

The standard Domestic Keder comes fitted with a tanalised and pressure treated timber base rail.  This can be upgraded to a galvanised box section steel base rail.
