Force gauge up to 35 lbs of measurement

Measure the force to open a door

To use, walk to the push side of the door. Using the gauge, push open the door and check the read out.

Changing the opening force requires adjustment of the closer spring. When a door is opened the internal spring expands creating resistance. This resistance is what the gauge is measuring. Reducing tension on the spring will reduce the opening force required to open the door.

Interior accessible doors should require no more than 5 lbs. of force to open. This applies to interior hinged doors and gates, as well as sliding and folding doors. The ADA Standards do not specify the opening force for exterior doors, though some state and local building codes may have requirements. Typical maximum opening force for exterior doors ranges from 8.5 to 10 lbs. Doors designated as fire doors must have the minimum opening force allowed by the local authority.
