Adjust counterbalance lift cables to create about 1” to 2” (25 mm to 50 mm) of initial exten-
sion spring stretch, with the door in the fully opened position.
Measure relaxed extension spring length for your door height and verify with chart. Spring
length must be the same for both extension springs to allow even door balance.
Carefully remove the locking pliers from the horizontal track and lower the door into the
closed position.
Once the door is closed, measure the extension spring length in tension for both sides. Using
the chart, verify the spring length in tension, is correct with your door height.
NOTE: It may be necessary to adjust spring length for proper door balance.

Now lift the door and check its balance. If the door is hard to pull down or lifts by itself, adjust
extension spring length by moving the “S” hook backward (towards the rear back hangs) to a
different hole in the horizontal angle.
If the door is difficult to lift or too easy to pull down, adjust extension spring length by moving
the “S” hook forward (towards the header) to a different hole in the horizontal angle.
IMPORTANT: WHENEVER ADJUSTING ExTENSION SPRING LENGTH FOR DOOR BALANCE,
ALWAYS OPEN THE DOOR TO THE FULLY OPEN POSITION AND RETURN THE LOCKING PLI-
ERS TO THE HORIzONTAL TRACKS BELOW THE BOTTOM TRACK ROLLERS.
If the door still does not operate easily, lower the door into the closed position and recheck
the following items:
1.) Check the door for level.
2.) Check the distance between flag angles – must be door width plus 3-3/8” + 1/4” – 0”.
3.) Check the counterbalance lift cables for equal tension- adjust by re-tieing the special
knot.
