Why Use A Door Opening Force Gauge?
According to the Americans With Disabilities Act requires that doors of a building be accessible to people with disabilities.
1. The Door Opening Force must be:
- Exterior hinged doors (Reserved, consult building code, local codes, and/or authority having jurisdiction)

- Sliding or Folding doors 5lb of opening force
- Automatic/Power Assisted Doors: (4.13.12) such doors shall not open to back check faster than 3 seconds and shall require no more than 15lbs to stop door movement. If a power assisted door is used, it's door opening force shall comply with 4.13.11 and its closing shall conform to the requirements in ANSI A156.19-1984.

How To Measure Opening Force On Door
1. Start by opening the door so that the door is cracked open. The door edge should be aligned with the frame edge (there should be a slight crack in the door opening, approximately 3" open).
2. Place the door gauge firmly above the door's cylindrical lock. If an exit device is on the door, place the gauge directly above the exit device chassis.
3. Push the door open slowly applying steady continuous force to the door.
4. When the door is approximately 70 degrees open, remove the force gauge to read the force.
Measuring the opening force on the door does take practice. It is best to test multiple times to ensure consistent results.
