The Adjustable Shed Base is specially designed to provide a quick and easy base for your corner building. Simply assemble the bearers in the kit as directed and attach each of the adjustable legs. Provided the ground is not more than 100 mm out of level the difference can be adjusted by moving the sliding discs on the legs and then locking them into place as the base is progressively hammered into the ground. No digging and no concrete to mix. This product is designed specifically for use with any of our appropriately sized buildings, it is not guaranteed to work with buildings from any other manufacturer.
