Barrier free openings: Take an opening force reading
from the pull on the door. If required, adjust the spring
force to meet the barrier-free requirement.
• Decrease force: turn counter-clockwise
• Increase force: turn clockwise
Depending on opening conditions, a door adjusted to
meet barrier-free forces may not have sufficient power
to reliably close and latch the door.
