Dual Side Post for Multiple Shelving Apparatus

Abstract

A dual side post, which is arranged for a multiple shelving apparatus constructed by two or more shelving apparatus each including a plurality of shelf supporting beams and a plurality of cross members, includes a plurality of vertical posts. Each vertical post has an inner attachment surface, a plurality of attachment slots spacedly formed at the inner attachment surface, and a retention slot formed on the inner attachment surface for coupling with the cross member. The attachment slots are lined up in two columns that the retention slot is located between the two columns of the attachment slots. One of the vertical posts serves as a common post that the two columns of the attachment slots thereof are arranged for respectively coupling two of the shelf supporting beams at opposite directions so as to interconnect two or more shelving apparatus to form the multiple shelving apparatus.
