As others indicated, this no longer includes instructions. If you are mounting these in a commercial building, chances are you are dealing with metal studs. To install in metal studs, you need to drill a one-inch hole in the exact center of the metal stud as you will have little to no room for error as most metal studs are around 1 1/2 inches wide or slightly larger. I used the DEWALT DW1629 1-Inch drill bit rather than the standard step bits because the step bits take away too much drywall. Attach the washer to the 3/8 inch bolt and then put the bolt through the speaker bracket hole. Attach the spring toggle to the end that comes out and insert the spring toggle through the one-inch hole. It will barely fit.
