Description
Complete base rail kits comprising of all the required parts – either timber or aluminium options.
Base Rails run around the entire Polytunnel framework. The polythene is then attached to the base rails and the height of the rail is adjusted to achieve a skin tight cover and a much easier option than re-trenching each time you replace a cover. Price is for both sides.
If your size is not listed, please contact us.
Please Note: It is essential that your foundations are either set in concrete, alternatively anchor plates or screw anchors have been used.
