Cantilever bases come in different heights, widths and lengths and are matched to the particular cantilever uprights you choose for your cantilever system. They allow you to store your material directly on them and they act as your first storage level within your storage system. The bases are attached to the vertical cantilever upright / tower and provide the strong foundation needed for your Cantilever rack system. All of our bases have anchor holes drilled in them to allow you to secure your cantilever bays to your concrete floor. Anchoring through the Bases will prevent your storage system from being moved from forklift impact while providing a strong and stable foundation for your Cantilever Rack System.
