Fitting the support bracket to the wall. It is setup for the typical 16" o.c. studs but my wall has 24" o.c. so needed some battens to adapt things. I mounted 2x4s across two bays of the studding with 3" lag screws. The instruction book give good guidance on the height to mount the brackets but I added a couple of inches to allow for putting the dust bin on castors someday.
