Need to attach wood 2x4 to poured concrete wall.
Torgue1,
I need some advice on mounting an electrical transfer device to a poured concrete wall. I have tried using mollies but drilling into this wall I keep hitting stones or something. I decided since the mounting holes for the transfer box are fixed and need to be placed accuractely that I should first mount 2x4's top and bottom or a 3/4 inch plywood as a mounting surface. However how do I attach the the 2x4's or plywood to this concrete wall. I am using a Dewalt 3/4" drill. Nails ? screws , mollies ??? Should I rent a hilty gun? Help I have burned up several concrete drill bits attempting to install concrete mollies

Yeah, mounting some treated 2x6's with a .22 nail gun would probably be your best bet. I'd glue behind them for extra measure.

Definitely use a hilty gun with the appropriate sized pins (nails). Your local hardware store should have a diagram that gives you the information on what size pins and shots for which application. Also a masonry bit really is only useful with a hammer drill, especially for your application. Carbon tipped bit at that. That said i think your best best would be to hilty 2x6's directly to the concrete. You will need a moisture barrier between the two surfaces though, being that the 2x6 is organic and the concrete is not. You will have mold growing on the 2x6 and that is no bueno

Thank You all for your advice. I will rent a hilty gun and attach the treated 2x6 to the wall using a barrier between the wall and the wood. Your advice is greatly appreciated. I have never run into this problem before now.You learn something new everyday. Thanks again for your help. Torgue1
