Step 1. Hold support plate (part B) in the desired location of entryway shelf. The support plate (part B) will be about 2" lower than the top of entryway shelf. Making sure support plate {(part B) is leveled, use a pencil to mark wall anchors locations using the support plate {part B) screw holes as a guide. We recommend using a leveler to make sure support plate (part B) is oriented correctly. Drill three 11/32" holes in these marked spots and tap wall anchors (part #1) into the drilled holes.
