I have a really large CD collection that I have decided I'd like to
display. I recently purchased some components of the Elfa
system from the Container Store to use as shelving. The
system basically consists of mounted standards which hold
shallow metal shelves (at least that's the way I'm using it.) The
standards are held to the wall by 5 screws, and I have three
total standards to mount all the shelves.
Unfortunately, only the left standard was the only one I was
able to hit the stud on. The middle and right one, I hit hollow
wall, and was forced to use Elfa's wall anchors, which seem to
work great. In addition to those anchor points, I chose to add a
few metal brackets that also mount to the hollow wall, but at
least provide a tiny bit more support to the center standard.
I have much of the CD collection on the wall now, and it seems
stable enough, but I noticed that the center standard has
creeped downward about an 1/8th of an inch from where I
originally mounted it. Is this normal? Should I be worried?
Just to give you an idea on the weight we are talking about. I
figured out that one shelf holds about 70" of CDs which based
on my crude scale, is about 40-45 lbs. I currently have 9 out of
12 shelves mostly full, so that's a little over 400 lbs currently
on the wall, with a potential to add about another 150 if I was to
fill out the space.
Help? Am I worrying about nothing?
