Federal Brace’s Stud Mounted Floating Shelf Bracket features a low profile floating configuration with high weight carrying capacity for shelving systems, work counters, and product display surfaces. The bracket features a 1/2" square rod for the support arm and 1/4" steel mounting plate. It is finished with a flat black powder coat paint, says the company. The 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.
