This shelf is entirely made from scratch, both the wooden board, as well as the metal bracket, are shop-made. They’re built using basic and widely available materials with no welding involved. The shelf bracket is held in place with 2 and not 4 screws, making drilling in concrete a little easier, faster and generating less noise. Unlike the other shelf I made in the past, this one uses a single and not double bracket rail, which seems to be less overkilling and more suitable for a light shelf like this. I am not a big fan of drilling in concrete…
