The closing force is adjustable from a size 1 to size 4, as outlined 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 Interior 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.

By law the Americans with Disabilities Act (ADA) may require that door closer installation comply with accessibility guidelines.
