fastening the 2X4s to the wall altogether -- you may be able to attach
them to a wooden sill plate or joist at the top (using an angle iron or
strap) and just let them rest against the wall. When loaded with
shelves they will want to pull away at the top, and push in at the
bottom.


I have some commercial standards with a hook on the top to dig into the
sill plate. Love them, hold lots of weight and are adjustable.
