Have need for shelves to hang on tilt-up concrete (not block) wall. Must be sturdy, but don't want supports at the corners. I'm thinking about some kind of triangular bracket anchored either from above (which holds a plank inside the bottom of the triangle) or from the back side (for which a plank would sit on the top of the inverted triangle):
|\\ | \\ | \\ | \\ =======
------- or =======
------- | / | / | / |/
(key: = is the plank)
Haven't been able to locate such locally (want to do this over the weekend upcoming).
Basically I want no forward supports, just wall attachments with some kind of diagonals.
Other ideas?
Thanks,
