Our Stud Mounted Floating Shelf Bracket by Federal Brace provides a low profile floating configuration with high weight carrying capacity for your shelving systems, work counters, and product display surfaces. The floating shelf bracket sports a 1/2" square rod for the support arm and 1/4" steel mounting plate. Finished with a durable flat black powder coat paint, this stud mounted bracket enhances your shelving system with a virtually invisible support. Our floating shelf bracket fastens to the support studs using 1/4 inch lag screws or lag bolts, and the 14" extended support arm will float up to an 18" shelf or work surface.
