Mounting Two Knobs on a Wide Drawer
When mounting knobs on wide drawers, it is sometimes helpful to mount two knobs. The trick here is to avoid mounting them too wide or two narrow.
One guideline is to look for the center of the door below (if applicable) and align vertically with the outer third of each door. If there are only more drawers below, then measure the drawer into 1/3s to find the best spot.
