Hanging melamine cabinets on concrete
I am an amateur woodworker and new to this forum. I have a question as to how best to hang cabinets to a concrete wall, without risk of them pulling out of the wall.
I am making a set of three melamine cabinets out of 3/4 sheets (1/2 for the back), and the largest has dimensions of roughly 3ftx3ft. I am hanging them on a concrete basement wall above a washer/dryer. The cabinets will not tie to the ceiling or floor.
To avoid conduit and other items, the backs will be offset from the wall by 1 1/2 to 2 inches.
I plan to make hangars by ripping a board in half at a 45 degree angle, with one piece attached to the wall and the other to the cabinet. I also plan to use concrete anchor screws.
My question is this. With such a large offset from the wall, the hangar stock will be fairly thick, which might put more stress on the anchor screws, even if I recess the screws into the hangar.
Is there a better way to do this or any further suggestions? Or am I worrying about nothing?
Is one hangar for each cabinet enough?
Also, I have had varying success with the concrete anchor screws (Tapcon). Occasionally, the screws do not grab as tightly as I'd like. Other times they are rock solid.
