SPRINGS SHOULD BE STRETCHED ENOUGH TO HOLD THE DOOR UP AGAINST THE HEADER IN THE OPEN POSITION, BUT THE AMOUNT OF STRETCH SHOULD NOT EXCEED 2" AT ANY TIME.

If a spring produces excessive noise when door closes, (a) brace door open (b) unhook spring at kicker and (c) twist the end of the spring 180 degrees IN THE DIRECTION IT TURNS MOST EASILY. Hook Spring on kicker and put bolt and nut in place.

STEP 2C - FOR SPRING ANCHOR

A certain amount of pre-stretch of the springs is required to keep the door snug against the header when open. At no time should there be more than 2" of pre-stretch.

There are two different methods to do this with the same basic hardware:
  1. Using a heavy screwdriver as shown, force down the lever plate. Raise or lower the upper nuts, with screwdriver still in place as required.
  2. Raise or lower the upper nuts with a wrench.
