How to fit inner deep Blum  Metabox drawer runners With the drawer box assembled, you are now ready to fit the packer and runners.

  • Some general observations for fitting the internal deep Metabox
  • The 25mm packer supplied with your kit goes on the hinge side of your unit, and allows the drawer to clear the hinges
  • To assist with the positioning of your drawer, please note that the measurement from the bottom of the box to the centre of the holes in the packer (and runner) is 150mm
  • The drawer can be positioned anywhere inside your unit as long as the packer is above or below the hinge plate.
  • Plan the drawer position depending on what you want to keep in the drawer.

  • The reference point or starting point for marking runners is the bottom of your drawer box
  • Decide on the position by measuring the combination of drawers you are fitting, or by holding the box in position as shown
  • When you have decided on the box position in the unit, mark the BOTTOM position on to the unit

  • From this bottom mark, measure up 150mm and draw a line inside the unit (use a set square if possible to ensure this line is at 90 degrees to the front of the unit)
  • Also draw a line 5mm back from the front of the unit
  • These lines mark the middle and the front edge of the packer
