Tools needed for installation:

  1. Chop box
  2. Hand Saw
  3. #2 Phillips screwdriver with or without drill
  4. Measuring tape
  5. Pencil
  6. Black marker
  7. 1-1/4” course sheetrock screws

Installing the Back-track:

The back-track holds the crown moulding and components in place and also acts a cable raceway. The wall side of the back-track is identified by 2 lines in the raceway. See photos below:       

Note: The back-track must be installed in full lengths where the crown moulding will be installed.

1. To install the back-track, cut small pieces (scrap) of the crown moulding and insert into the back-track approximately every 2′.

2. Place the back-track between the ceiling and wall, hold cut piece of crown moulding flush to the wall and ceiling and install a 1-1/4” course sheetrock screw.

3. Continue to install screws every 16” working towards the outer edges.

4. Remove blocks by inserting a screw driver between the crown moulding and back-track, pulling toward you. Back-track is now ready for full lengths.

Walls 16’ Long and Under:

In the steps below we recommend marking the back-track using a black marker. These markings help identify location of crown moulding when installing, and removal and replacement for future upgrades, painting or fiber-optic/cable installation.

1. Measure the walls to be trimmed and obtain the linear footage needed.

2. Divide this number in half, mark and identify the center line on the back track.


3. Measure and mark your back-track for the appropriate space needed for each component.

4. Measure the distance between component markings. This is the length you will need to cut your moulding.

5. After you have made your cuts, simply line up one end of your crown moulding to your mark and press it into the back track.


6. When all your linear pieces are installed, you can install all seam covers and corners.
