Steve, not sure which TH you have but I have a RW and installed a closet in our garage. I placed the hanging/shelving unit parallel to the ODS wall under my loft since I still needed room to park the HD. I tied into the metal supports for the loft since they were the easiest to find and then, using plumber's tape, tied the unit to the floor. You would have to extend some type of supports that reached the "ceiling" for your bench install. Good luck with your mod>
