Selby's best-selling Complete Shelf Magic Shelf Support System offers yet another example of our hardware wizardry! Add some decorative dash to a room using these concealed shelf supports. The shelves will look like they are floating. In order to entirely conceal the hardware, the shelf must be at least 1-1/4" thick. Includes 1 mounting bracket, 1 support rod, 6 screws and 6 plastic screw anchors. Mounting/Installation: Screw anchors are placed in the wall in 6mm (15/64") holes and the mounting bracket is affixed to them. The support rod is fixed to the mounting bracket with set screws that are vertically and horizontally adjustable. Holes (12mm diameter x 3-5/8" deep) are drilled into the rear of the shelf to seat the rod. For full concealment, a 7/8" wide groove x 3/16" deep may be cut into the shelf back.
