  • When marking on the unit where the bottom of your drawer front comes to, it is important to remember the top clearance gap. This gap is usually 4mm - 5mm, and can vary from one manufacturer to another.

  • For Tandembox deep runners, you come up 40mm from this mark.
  • Extend this 40mm line inside the unit for 200mm to 300mm
  • PLEASE ENSURE that this line is at 90 degrees to the front edge of the unit (using a set square if possible)
  • PLEASE NOTE, if this line crosses over any of the original holes in your unit, and they will get in the way of the new holes, move the line UP 10mm approx. Remember to go up the same amount on the other side.
