No chance of those cheap magnet things finding a drywall screw and going every 6 or 8" to the next web?
Or using the screw in type drywall plugs that have a capacity of 75lbs?
I was going to suggest the magnet approach also. Drywall plugs would be iffy for Closetmaid, in my thinking. An alternative would be to use an anchor into the concrete.
galnar, what part of the closet system are you looking to install, the header type channel that the shelf support channels hang from? If so, I suggest you take a hard look at anchoring into the concrete. If you're hanging closet rods keep in mind that clothes are quite heavy. The anchors I've used, and really like, are the Redhead 3/8" drop in threaded anchors. You drill a 1/2" hole in the concrete and push the anchor into it, then use a 1/4" rod and hammer to set it. Then use a 3/8" bolt of whatever length needed. With these anchors you don't have to be concerned about getting the hole depth just right, just deep enough to be solid. The 3/8" size of bolt may be an issue, but unfortunately the anchors don't come smaller.
