How to adjust a hollow metal door closer

How to adjust a hollow metal door closer

Hollow metal doors are commonly used in commercial and industrial settings due to their durability and security features. One important component of a hollow metal door is the door closer, which helps to control the speed at which the door opens and closes. Adjusting the speed of a hollow metal door closer is essential to ensure that the door operates properly and meets the requirements of the American National Standards Institute (ANSI). In this article, we will discuss how to adjust the speeds of a hollow metal door closer and the ANSI requirements that must be met.

Adjusting the Speeds of a Hollow Metal Door CloserThere are several factors to consider when adjusting the speed of a hollow metal door closer. The speed at which the door opens and closes can be adjusted using two different valves on the door closer: the closing speed valve and the latching speed valve.

The closing speed valve controls the speed at which the door closes from the point where it is fully open to approximately 10 degrees from the closed position. The latching speed valve controls the speed at which the door closes from the 10-degree mark to the point where it latches.

To adjust the closing speed valve, locate the valve on the door closer and turn it clockwise to decrease the speed or counterclockwise to increase the speed. To adjust the latching speed valve, locate the valve on the door closer and turn it clockwise to decrease the speed or counterclockwise to increase the speed. Adjust the valves gradually until the desired speed is achieved, testing the door after each adjustment.

It is important to note that the speed of the door closer should be adjusted according to the weight and size of the door. Larger and heavier doors may require a slower speed to ensure that they close properly and do not slam shut.

ANSI Requirements for Hollow Metal Door ClosersThe ANSI provides guidelines for the installation and operation of door closers on hollow metal doors. These guidelines help to ensure that the door closers are installed and adjusted correctly to meet safety and accessibility requirements.

One important requirement is that the door closer must be installed in a location that allows for easy operation by individuals with disabilities. This includes ensuring that the door closer is not installed too high or too low on the door and that there is sufficient clearance around the door to allow for easy maneuvering by individuals with disabilities.

Another requirement is that the door closer must be adjusted to close the door at a speed that does not exceed 5 feet per second. This is to prevent the door from slamming shut and potentially causing injury to individuals in the vicinity of the door. The door closer must also be adjusted to prevent the door from opening too quickly or too forcefully, which can also pose a safety hazard.

In addition to safety requirements, the ANSI also provides guidelines for the durability and longevity of door closers. Door closers must be tested and certified to meet certain standards for durability and resistance to wear and tear. This helps to ensure that the door closer will operate effectively over time and does not need to be replaced frequently.

Conclusion

Adjusting the speed of a hollow metal door closer is an important step in ensuring that the door operates properly and meets safety requirements. By following the guidelines set forth by the ANSI, building owners can ensure that their door closers are installed and adjusted correctly and will operate effectively over time. If you are unsure how to adjust the speed of your door closer, it is recommended that you consult with a professional installer or technician who can provide guidance and assistance.
