The one welded to the wall end of the rod with the two screw holes in the top edge of it that allow you to attach the rod to the wall.
It actually tries to pull the screws out of the wall because the metal plate pivots along the bottom edge of the plate as the shelf is loaded.
Nothing like in fact.
Here's one example :
It is, that plate is covered by the shelf.
That's much harder to install, getting the rod in the right place to fit into the hole in the shelf and getting it at right angles to the wall in both directions.
Nope, its covered by the shelf.
The plate is much smaller and is covered by the shelf.
So the plate is nor bigger than the thickness of the shelf, nowhere near big enough to prevent leverage.
Consider how deep the shelf is. Consider the small distance from the rod to the screw along the tiny plate. Consider the huge leverage ensuing from this. The screw would be easily pulled straight out of the wall.
And looks much worse than a floating shelf.
If you would go look at the LV link a zillion folks have pointed you to, you would realize that's exactly what it is sized for.
And, it's sufficient leverage for 100-lb distributed load on a 5-1/2" wide shelf with two arms.
This has gone beyond ridiculous.
It looks like a shelf, instead of some new age s*it out of star trek.

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.
There will be a bit of friction between the shelf mounting plate and the wall itself if the screws are tightened properly in the first place.
I'll stick to proper brackets which allow for leverage.
If the walls are anything like UK walls, the wood used is cheap softwood and can't take much force.
Trivial to check if it survives a 100lb load fine.
I havent. The spec uses pounds so I used that.
You might aswell ask me to calculate if a torch could be seen from the moon.
If I saw a spec written in French, I wouldn't use it. I'd write it in here in English.
With a huge force due to the amplification from the leverage. Those shelves are just like crowbars pulling nails out of a wall.
Then get a nice looking bracket.
Trivial to test the claim and see that its accurate.
Irrelevant to something entirely mechanical and like a shelf bracket.
And you will find that they don't work very well, for a reason.
No reason why it can look better and serve its purpose too.
All of my roof gutter downpipes are completely invisible. Looks much better than the stupid abortion with them on the wall.
You really are gullible aren't you?
