Step by Step Instructions

1 Measure your door frame
2 Check the frame is level
3 Measure the height for the tracks
4 Attach the tracks to door frame
5 Measure and mark the doors
6 Screw on the rollers
7 Hang your doors on the tracks
8 Install the door guides
9 Adjust the doors
10 Install the centre bump stops
11 Install the end bump stops
  • Step 1. Measure your door frame

    Measure the centre of your door opening, above the doorframe, and place a mark there. Check the instructions for the height needed above the door and the recommended floor clearance.  

  • Step 2. Check the frame is level

    Use your spirit level to make sure the timber that you’re fixing the track to is nice and level. 

  • Step 3. Measure the height for the tracks

    Measure and mark up the correct height for the tracks. 

  • Step 4. Attach the tracks to door frame

    Then predrill and screw the tracks into position on either side of the centre point. 
  • Step 5. Measure and mark the doors

    According to instructions, measure and mark the position of the rollers onto the top of your doors. 

  • Step 6. Screw on the rollers

    Then pre-drill the marks you’ve made and screw your rollers on. Repeat on both sides of each door. 

  • Step 7. Hang your doors on the tracks

    Loosen off the rollers and then use them to hang your doors on the tracks above the doorframe. 

  • Step 8. Install the door guides

    Install a door guide at the base of each door by screwing them to the wall. This will hold the doors in place and stop them from wobbling around. Make sure you consider the finished height of your door and any floor coverings.

  • Step 9. Adjust the doors

    Use your spanner to make adjustments to the door rollers, ensuring both doors are the same height and perfectly in line. 

  • Step 10. Install the centre bump stops

    Install the bump stops in the centre and at the end of the tracks to stop the doors rolling too far in either direction. Align them over the pre-drilled holes in the centre of the tracks and screw them on. 

  • Step 11. Install the end bump stops

    Align the end bump stops over the pre-drilled holes at the end of each track. Then screw them on. These will also secure the end of each track to the wall.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
