closers is adjustable from a size 1 to a size 6,
as outlined in ANSI Standard A156.4. When
these series of door closers are installed and
adjusted to conform to ADA reduced opening
force rerequirements (5 lbs max.) for interior
doors, they may not have adequate closing
force to reliably close and latch the door. Power adjustments
charted on Page 5 are recommended, where possible, to
insure proper door control.
