Step 1: Assess the Fill Piece of the Cabinet

Stock or ready-made cabinets may include a fill space, an extra-wide face piece that makes it easier to fit and center cabinets in the available space. To determine how much of the fill piece is needed to best fit the available space, begin by measuring the width of the fill piece.

Step 2: Determine How Much to Cut

Based on the size of the fill piece and available space for the new cabinet to meet a wall or other cabinetry, calculate the amount to cut from the fill piece. In this case, only 1/4" of a 3-1/4" fill piece was needed to make it match the other cabinetry.

Use this measurement to set the table saw. In this example, the table saw fence is set at 3" away from the blade for an accurate final dimension. Keep the table saw unplugged when not in use, especially when adjusting the distance of the fence from the blade

Step 3: Prepare the Cabinet

Cover the entire face of the cabinet, including the fill piece, with painter's tape to protect it from scratches as it goes through the saw. Low-tack painter's tape is gentler on the cabinet finish than duct tape or other tapes.

Step 4: Trim the Cabinet

Set the cabinet face-down on the table saw to make the rip cut. It's very important to have at least one helper available to keep the piece lined up and make the cut cleanly and safely. Cut the fill piece, using the pre-set saw fence as a guide

Step 5: Find the Studs for Cabinet Positioning

Locate the wall studs where the cabinet will be installed and transfer those measurements to the inside of the cabinet. Tip: Once you find the first stud, the others should be 16" apart. It's important to allow for the width of the stud when transferring the measurements as the cabinet must be properly secured to the stud to hang safely.

Step 6: Drill and Hang the Cabinets

Using the marks inside the cabinet as a guide, drill pilot holes through the back of the cabinet.

Check to make sure the pilot holes will line up with the studs in the wall by re-measuring the distance between the studs on the wall and the distance between the holes in the cabinet. Drive cabinet screws to attach the cabinet to the wall.
