This is primarily important if you are planning on installing a sink into one of your cabinets, as you will need to place that cabinet where it can connect easily to the plumbing. You should be able to see the pipes or openings coming up through the floor. Do not draw the lines for your suspension rails freehand or even using just a ruler. In order for your cabinets to be straight and level, your suspension rails will have to be as level as possible. Use the spirit level to carefully mark the lines for your suspension rails across the wall.  You will need one line to mark the bottom of the base rail and another line to mark the bottom of the upper rail.  The bottom of the base suspension rail should be 32 3⁄16 inches (81.8 cm) from the highest point of the floor.  The bottom of the upper suspension rail should be 82 3⁄16 inches (208.8 cm) from the highest point of the floor. If you don’t know where the studs in your wall are, use an electronic stud finder to locate them. Make sure you mark the studs so you can easily find them when installing the rails, perhaps with a color that shows up clearly against the wall. You will need to put your fasteners through the studs to make your cabinets as secure as possible. Find the dimensions of your cabinets on the box or manual, or measure your assembled cabinets with measuring tape. Make sure you’re noting which cabinets will need to have holes for utilities connections. You’ll need to place these cabinets over the connections you marked earlier. If you need to have more cabinets with holes, you’ll be able to saw openings later. Some of your cabinets should come with pre-made holes. Plan to be those cabinets where the connections need to be.
