I purchased three 9 inch, three 18 inch, and one 24 inch towel bars for two newly remodeled bath rooms. They are sturdy and have the modern look I wanted.  The only issue I will have is that they will be difficult to remove if I ever have the need to take them down.  they do not have a simple screw to release them like most towel bars do.  there is a tab that is tight and may be difficult to access depending on where they are mounted.  a template for spacing the posts would have been helpful.
