Choose how many panels you are mounting and get the exact position — along the tape measure — to mark each rail. You always measure to the left side of the rail (green line); the red dot is the centre.
For the next panel, add the step P + G to each line.
| No. | Position | Rail | Measure to (mm) |
|---|
Each value is the distance from the start (0 mm) to the left side of the rail. Lay out the tape, mark the point and align the left edge of the rail with the mark.
We measure to the left side; the centre (red) is 72,5 mm away.
