ABOUT

When it comes to door closers, the choice between hold open and non-hold open models can significantly impact the functionality and convenience of a space. Door closers are essential devices that ensure doors close securely and safely, but the decision to use a hold open or non-hold open closer depends on various factors, including the intended use of the door, building codes, and user preferences. This article will explore the differences between these two types of door closers, their applications, and the benefits and drawbacks of each.

Functionality and Mechanism

Hold open door closers are designed to allow doors to remain open at a specific angle, typically 90 degrees, until they are manually closed. This feature is particularly useful in high-traffic areas where doors need to stay open for extended periods, such as in hospitals, schools, or office buildings. The mechanism behind hold open closers involves a hydraulic or pneumatic system that can be adjusted to hold the door open at the desired angle. When the door is pushed beyond this angle, the closer automatically engages and closes the door smoothly.

On the other hand, non-hold open door closers do not have the capability to hold the door open. These closers are designed to close the door immediately after it is released, ensuring that the door is always securely closed unless manually held open. This type of closer is commonly used in areas where security and energy efficiency are priorities, such as in residential buildings, storage rooms, or fire-rated doors. The mechanism in non-hold open closers is simpler, as it only needs to control the speed and force of the door closing, without the added complexity of holding the door open.

Applications and Use Cases

Hold open door closers are ideal for environments where doors need to remain open for extended periods to facilitate the flow of people or equipment. For example, in hospitals, hold open closers are often used on doors to patient rooms or operating theaters, where medical staff may need to move quickly between rooms with their hands full. Similarly, in office buildings, hold open closers can be used on doors to conference rooms or break areas, allowing for easy access during meetings or events.

Non-hold open door closers, however, are better suited for areas where doors should remain closed unless in use. This is particularly important in residential settings, where security and privacy are concerns. For instance, non-hold open closers are commonly used on front doors, bedroom doors, or bathroom doors in homes. In commercial settings, non-hold open closers are often used on fire-rated doors, which must remain closed to prevent the spread of fire and smoke. Additionally, non-hold open closers are used in storage rooms or utility closets, where doors should remain closed to maintain security and prevent unauthorized access.

Benefits and Drawbacks

One of the primary benefits of hold open door closers is their convenience. They allow doors to remain open without the need for doorstops or other devices, which can be cumbersome and unsightly. This can be particularly useful in high-traffic areas where doors are frequently opened and closed. Additionally, hold open closers can improve accessibility for individuals with disabilities, as they eliminate the need to manually hold doors open while navigating through them.

However, hold open door closers also have some drawbacks. They are generally more complex and expensive than non-hold open closers, due to the additional mechanism required to hold the door open. This complexity can also make them more prone to mechanical failures, which may require more frequent maintenance. Furthermore, hold open closers may not be suitable for all environments, particularly those where doors must remain closed for security or safety reasons.

Non-hold open door closers, on the other hand, are simpler and more cost-effective. They are less likely to experience mechanical failures, as they have fewer moving parts. This makes them a reliable choice for areas where doors must remain closed, such as in residential or fire-rated applications. Additionally, non-hold open closers are often more energy-efficient, as they ensure that doors are always closed, reducing the loss of heated or cooled air.

However, non-hold open closers may not be as convenient in high-traffic areas, as they require doors to be manually held open if needed. This can be inconvenient for individuals carrying items or for those with disabilities who may struggle to hold doors open while navigating through them. In such cases, additional devices like doorstops or automatic door openers may be required, which can add to the overall cost and complexity of the door system.

Building Codes and Regulations

Building codes and regulations often play a significant role in determining whether a hold open or non-hold open door closer is required. For example, fire-rated doors are typically required to have non-hold open closers to ensure that they remain closed in the event of a fire, preventing the spread of flames and smoke. Similarly, doors in certain types of buildings, such as hospitals or schools, may be required to have hold open closers to facilitate easy access and egress during emergencies.

It is important to consult local building codes and regulations when selecting a door closer, as failure to comply with these requirements can result in fines or other penalties. Additionally, building codes may specify the type of closer required based on the location and function of the door, so it is essential to choose a closer that meets these specifications.

Conclusion

In conclusion, the choice between hold open and non-hold open door closers depends on a variety of factors, including the intended use of the door, building codes, and user preferences. Hold open closers offer convenience and accessibility in high-traffic areas, while non-hold open closers provide security and energy efficiency in areas where doors should remain closed. By understanding the differences between these two types of closers, you can make an informed decision that best meets the needs of your space.
