Install Remaining Cabinets After corner or end cabinet(s) are fastened, continue installation with remaining adjacent cabinets. End Wall Filler Wall Fillers are available to fill gaps between the end of a row of cabinets and a 90 wall. Prepare Backer Board Figure 11 NOTE: A Backer Board is required behind the Wall Filler only if the Filler is wider than 3". Attach Backer Board before installing the final cabinet. To mark Wall Filler and Backer Board positions: Run a straight edge across the space between the wall and the closest cabinet. On wall, mark behind the Straight Edge. Draw a straight, vertical line from this mark. Align front of Filler on this mark. Mark behind the Filler for front position of the Backer Board. Attach Backer Board to wall so it is plumb. Be sure that Backer Board is wide enough to be fastened to the nearest wall stud. Install Final Cabinet Shim, level, and install the final cabinet. Measure Wall Filler Figure 12 With final cabinet in place, measure gap between the wall and the top and bottom of the cabinet. If wall contour is even, use this dimension to mark and cut the Filler. Scribe Wall Filler For Irregular Wall Figure 12 If the wall contour is irregular, you'll need to clamp the Filler parallel to the cabinet, then use a compass to scribe the wall contour onto the surface of the Filler. NOTE: Scribing is required only if the wall surface is irregular. Before scribing, run masking tape down the Filler where the scribe mark will be. This tape will show the mark better and will protect the Wall Filler surface when cutting. Clamp Wall Filler to front of the final cabinet so its uncut edge is parallel to the cabinet. Use compass to scribe wall contour onto the Wall Filler. NOTE: Cut conservatively! It is better to cut too little than to cut too much. Final fitting may require edge sanding. Cut Wall Filler to width following the scribe mark. Put Filler in position. Drill and fasten between final cabinet and Filler edge. Use finish nails to tack Wall Filler to Backer Board, if necessary.
