Locate and Mark Wall Studs Figure 6 Typical wall construction places wall studs on 16" centers. This means that every 16" you have the center of a 2 x 4 wall stud to support your cabinets. To locate a wall stud, there are wall stud finder tools available or you can tap on the wall and listen for a "solid" sound. Once you have located a wall stud, drive a long thin finish nail or use a power drill with a small bit to drill into an area just below the Base Cabinet Level Line that will be covered by the cabinets. It will require several holes spaced close together to find the outside edges on the wall stud to determine its center. Measure out 16" from this point and repeat to be certain that you have contacted the center of the wall stud. Mark the location. Continue this process to locate all wall studs behind your cabinets. Once all wall studs are located, use a 4' level to draw vertical plumb lines at each wall stud from the floor to a few inches above the Top of Wall Cabinet Level Line. Soffits and Low Ceiling Conditions Figure 7 If wall cabinets are to be mounted under soffits or ceilings lower than 8', you must first determine the lowest point under the soffit or ceiling. Measure up from your Base Cabinet Level Line in several areas to locate the lowest point. Mark this point. Mark other points at the same distance up from the Base Cabinet Level Line. Snap a level chalk line between these points. This will be the Top of Wall Cabinet Level Line. Measure 30", 36", or 42" (the height of your wall cabinets) down from this line to confirm the distance between the Bottom of Wall Cabinet Level Line and the Base Cabinet Level Line. You must have a minimum of 17 1/2" between counter top and the wall cabinet for proper appliance garage operation. With Base Cabinets You Must Have These Dimensions: Figure 8 30" Wall Cabinets Require 84" from top Wall Cabinet Level Line to Floor High Point Level Line 36" Wall Cabinets Require 90" from top Wall Cabinet Level Line to Floor High Point Level Line 42" Wall Cabinets Require 96" from top Wall Cabinet Level Line to Floor High Point Level Line
