I've had a shelf come free from the wall on which it was anchored. The shelf is fairly deep (~2') and solid wood, so it's heavy, and it's meant to take some weight (think like a breakfast bar).
The two 90º triangle brackets supporting the shelf pulled the anchors and bolts right out of the brick wall when somebody leaned on it.
Now I have four ~3/4" holes in the brick from the previous anchors. The previous anchors look like this:
They've left pretty smooth holes. So I now need to work out the best way to re-use those positions on the wall for new, more appropriate/stronger anchors. I could drill out new holes in the brackets to avoid the existing holes in the wall, but I'd rather not if possible.
Any suggestions would be appreciated!
Update: A photo of the actual hardware. They're 1/2" holes, according to the writing on the anchor.
