Because I’m always operating with more than 1 open up tube of silicone or caulking in my store, I wanted a much better way to keep them when not in use. Now I hold them in a 12×4-inch size of ¾-inch plywood with holes slice to the dimensions of the tubes. I mount the plywood on a shelf. They will not roll away or tip in excess of, and there are no more obstructions or inconvenience.
