The closing force for series QDC111BF door closers is an adjustable form of a size 1 to a size 6, as
outllined in ANSI Standard A156.4. When these series of door closers are installed and adjusted to
conform to ADA reduced opening force requirements (5 lbs max) for interiror doors, they may not have
adequate closing force to reliably close and latch door. Power adjustments charted on this page are
recommended where possible to ensure proper door control.
