Step 25
Draw or texture a central horizontal line along the length of
the springs. This line is used to easily identify the amount of
tension you have put on the door each spiral reflects one turn
of tension.
Springs must be tensioned in the direction they
are wound.
Insert a winding bar into the hole of the spring block and wind
1/4 of a turn, now insert a second winding bar and continue
turning repeat this process until desired tension is achieved.

Step 21
Secure the spring anchor plugs to the centre bearing. Locate
the left wound spring to the right side of the plate and the
right wound spring to the left of the plate. If your door only
requires one wound spring locate it to the left or right as
detailed above. Slide the completed spring assembly over the
shaft and slide into place the cable drums at each end. Ensure
that the correct drums are on the right ends as marked.

Place the shaft assembly over the horizontal tracks and slide
one end through the bearing plate with the greatest side
clearance, then insert the opposite end into its bearing plate.
