Hard mounting has its obvious advantages and can be done from the front or back. To mount the corbels from behind, use multiple screws or bolts that are long enough to enter the corbel but not so long as to go all the way through the corbel. If you can't attach a corbel from the back, a front mount is required. You can simply screw into the front of the corbel and cover the screw heads with putty and sand. Be aware of what you are screwing into and make sure you are going at least 1 1/2 into the mounting surface.
