I installed a pot rack over a kitchen counter in my condo which has
concrete ceilings. I asked a guy at a hardware store what I should do
and he recommended I use two plastic anchors, and that they should both
be able to handle 50 pounds.
I drilled holes in the ceiling (took a very long time, was very hard)
and then hammered the anchors in and screwed the hooks that support the
pot rack. It seemed very sturdy.
On of the anchors was flush against the ceiling and the other was about
1 mm out.
4-5 months later I have noticed that both anchors appear to be 3-4mm
out of the ceiling. I've taken down the pot rack in fear that it might
come loose and crash down on the marble countertop.
Does anyone have any suggestions on what I should do? Is this normal?
Can I expect it to hold the load?
Should I add two more anchors to support the weight?
