However, such known systems has several disadvantages including substantial effort needed to precisely align the units for assembly/attachment, as well as substantial effort needed to reconfigure or separate the units due to the fasteners and brackets used. As such, breaking down the system to reconfigure, store, or relocate it is a difficult activity. As such, multiple systems or customized systems are purchased and installed at a greater expense than if a single system could be quickly and easily assembled, disassembled, reconfigured, stored, relocated, or the like.

It would also be advantageous to provide a link or coupling member for connecting sectional units of a modular food service system. It would further be advantageous to provide a connector link that assists in aligning and coupling the adjacent units and reduces or minimizes the effort required to install. It would be desirable to provide for a modular service system having one or more of these or other advantageous features. To provide an inexpensive, reliable, and widely adaptable link or coupling member for connecting sectional units of a modular food service system that avoids the above-referenced and other problems would represent a significant advance in the art.
