Blind Shelf Supports

Made of zinc-plated steel, a pair of these blind shelf supports will invisibly hold a 1" or thicker shelf. Each mounting plate is anchored to the wall studs with two flat-head screws, and the projecting 5" long hex posts slip into 7/16" holes drilled in the back side of the shelf. Even if your holes end up slightly undersize, the corners of the hex post will cut their way in.
