Anchoring Shelf Brackets to Concrete
Suggestions for firmly attaching steel angle countertop supports to a poured concrete wall. February 19, 2011
Question
I’m mounting KV2083 steel brackets to a poured concrete wall to support countertop in a high school lunch area. The top is 18" x 41' and supported entirely by about 18 brackets. What would you use for anchors/fasteners?

I would use a wedge bolt. We use them around the shop all the time. They hold extremely well and can be removed and re installed.

Check out Hilti. We've had great luck with many of their anchors. They make all kinds of wedge type with different heads.
From contributor S:
How about mounting some 1/2", or 3/4" ply edgebanded and ramset or tapconed to the concrete, then easily attach the slides? It makes adjustment of the slides, should it be necessary. It’s much easier than trying to fine tune a tapcon in cement. You can shim the ply to adjust for out of plumb concrete.
