The Floating Shelf Clamp System from Federal Brace is a uniquely adjustable bracket that comes with your choice of a shelf insert. The most prominent feature of the system is the ease of usability. The system comes with all the necessary fasteners needed for installation. The Floating Shelf Clamp System is ideal for tight spaces, the company says. It helps provide a valuable option that embraces small spaces instead of being intrusive. This shelf has a carrying capacity of 30 lbs per pair, 15 lbs singular with the shelf plank centered. The shelves come in three different materials: maple, pine, and black MDF. The maple and pine options are unfinished, which allows for staining.
