A.Randy Palumbo responds: When faced with a granite countertop, the trick is to provide a wood base to accept the 3/4-inch-long screws I typically use. Most granite countertops have a 3/4-inch buildup on the edge. When the buildup is not too wide I attach a strip of 3/4-inch cabinet-grade plywood behind this edge, using silicone as the adhesive.

When the buildup is too wide, I have no choice but to drill small holes into the underside of the granite. I then insert plastic anchors, secured with epoxy, to accept the screws.
