Slide the second drawer back onto its runners. Place the two, one dollar coins on the left and right hand side on the top of the bottom drawer, these are your spacers. Place the top drawer on top of the coins and measure that it’s even with the bottom drawer. Clamp the drawer to the top rail and use a rubber mallet to gently tap it into place and make sure that it’s in line with the bottom drawer. Drill four holes, two on the left side - top and bottom and two on the right side – top and bottom, making sure you don’t drill through the panel. Attach the panel to the cabinet using your drill and screws. Then remove the clamps and the coins.
