I have a set of bypass closet doors and need to attach the little guide in the center to the floor. The floor is carpet and pad over concrete.

My basic idea is to attach a piece of 1/2" oak to the floor on top of the carpet by drilling holes through the carpet into the concrete with a hammer drill, drop in sleeves, then screw the oak and the guide to the concrete over the carpet all in one shot. This would require pretty precise alignment of the holes.

Another idea would be to make a couple holes in the concrete and screw the oak to the concrete floor first. Then I would make a separate set of screw holes in the oak for the guide. This would require less precision attaching the oak to the concrete, and allow easier alignment of the guide.

Make sense? Any suggestions?

Thanks!

I'd go with your second idea. Be carefgul drilling through carpet, the bit can snag a thread and give you a run in the carpet befire the drill can be stopped. When I drill in carpet I usually take a red hot nail head and melt myself a hole through the carpet and seal the edges at the same time. Doesn't work so well on wool.

Thanks for the feedback, and the helpful hot nail trick.

Any thoughts on size or type of concrete anchor? Based on my very limited knowledge (what I found on the net today), I was planning to use something I can drop into a pre-drilled hole and use a regular wood or sheet-metal screw. Or do you have a better idea?

I buy small packets of plastic anchors and they usually come with the recommended screw. I would not use a wood screw but sheet metal is probably just fine.

I'll look for those, thanks
