I've installed some but very little of this product. They sell two-hole "top hat" straps for securing to walls/ceilings however if Joe is right on this (and he probably is) that approach will look much better. My local HD, Lowes and Ace all carry the Wiremould brand incl. every box/fitting available. In fact, I noticed that most of those stores that I've been to in other localities also carry them. Maybe yours are simply hiding it.You should be able to run some screws through the stickon to hold it up.
