Abstract
A support tube for use with a support tube surface area assembly such as a shelf, a portion of a furniture article, or other structure, comprises a first end, a body section, and a second end. The first end and second end of the support tube are outwardly flared to provide a tapered interior area into which a first and a second accessory element, such as a nut and bolt, may be inserted. The accessory elements are enclosed in the tapered interior area by a crimping and flattening of the lips of the first and second end such that they form an interiorly extending flange partially encapturing the accessory elements. A method for making the support tube is disclosed as well a shelf structure or furniture article assembled with the support tube.
