What's ridiculous is you not realising that a 12 inch shelf pulling
against a 1 inch bracket is a LOT of leverage.* The bracket has to be
about the same height as the depth of the shelf.

I previously posted the calculation above that shows actual moment arm
is well within the product specs with at least a 2X safety margin.

And, YET AGAIN READ THE BLODDY SPEC SHEET!!!! -- the product description
shelf depth is 5-1/2" not 1-ft.

Spec sheets can't break the laws of physics.
And they're not coming even close to doing so here -- the rated load for
the dimensions is at least 2X less than the lower range of holding power
in soft pine as shown previously.
