What Is A Door Closure

A door closure is commercial product used on doors in public buildings, office spaces, warehouses, businesses, and more that automatically close the door once the person has passed through the doorway. Door Closures are considered manual, meaning that they do not require electricity to operate. Instead they rely on simple physics, more specifically hydraulics and kinetic energy from an internal spring. Door closures are the #1 automatic closing device used on commercial doors since they can easily regulate the various closing speeds involved in safely closing the door.

The Purpose Of Door Closures

1. Door Closures Help Prevent Injuries Among Disabled Pedestrians, Children, and The Elderly

Among the top reasons for installing a door closure is definitely safety. As a building owner, business owner, or any person of authority at your building, safety is always a concern. After all, you don't want anyone getting hurt at your location. Injuries can often turn into law suits, which is something no one wants to be a part of. A correctly adjusted door closure can regulate the closing speed of the door, once it is opened. Also, the door closure is designed with an internal tensile spring that compresses as the door is pulled or pushed open by a pedestrian. This makes it difficult for a pedestrian to swing the door open too fast, due to the internal door closure spring. Without a door closure on the door, a pedestrian exiting the door could open the door too quickly, potentially hitting another person trying to enter the building. Likewise, other factors such as wind, could catch the door and swing it open to unsafe speeds causing pedestrians near the door to get hit or their fingers smashed if the wind pushes the door closed too fast. Many dangerous situations can arise if a door closure is not used on a door.

2. Keeps The Door Closed In Case Of Fires

Another major reason to use a door closure is fire suppression. NFPA or the National Fire Protection Association requires that all fire doors use a door closure. The reason for this is a fire door is manufactured from special fire resistant material. A fire door's sole purpose is to slow or prevent the spread of fire and smoke. As a result fire doors must always be closed and latched after the door is used. This is why a door closure must be used, since it automatically closes the door each time a pedestrian passes through the door way. There is one major detail to always remember. Not all door closures are fire rated. The UL10c is a sticker that is placed on door closures if they are fire rated. If the door is a fire door then the door closure must be fire rated in order to be installed on that door.

3. Reduce Building Energy Consumption

During cold Winter months, building use a furnace on the HVAC system to generate heat inside of the building keeping it warm for pedestrians inside. Similarly, during warm Summer months, a building's HVAC system provides cool air within the building to keep the temperature tolerable for pedestrians. A door closure on all the building's exterior doors will ensure that the exterior doors are always closed and latched when pedestrians are not using them. This results in massive energy savings in your building. With an open door, the HVAC system will have to work much harder in order to maintain the desired inside building temperature on the thermostat, resulting in very high utility bills.

4. Provides Accessibility To The Disabled

According to the ADA or the Americans With Disabilities Act, an ADA compliant interior door 1) Must not require more than 5 lbs of opening force and 2) Must take atleast 5 seconds to close from the 90 degree full open position to 12 degrees. The 5lb opening force ADA requirements is essential in order to ensure that a person in a cane, wheelchair, or walker will be able to open the door. A door with a greater opening force such as 30lbs could result in the disabled pedestrian not being able to open the door. As a business owner, you never want to have your business inaccessible to any pedestrian.

5. Provides Security To Your Door

When you think of a secure door, you think of a door that is locked and can only be accessed by specific personnell. It can be argued that a door closure is the most important door component for door security. A typical security door will have some form of door lock such as keyed mechanical door lever handle or an electronic magnetic lock or electric strike lock. Access to a security door is often achieved by a key pad with a special pin code that must be entered, or a card reader which requires the pedestrian to present a security card near the card reader device. Having a door closure on a security door, ensures that the door is always latched and closed after a pedestrian uses the door. Without a door closure, a security door would never close unless the pedestrian manually closes it after they use the door.

How To Order Door Closures

1. Identify Door Type

Is this door a wood door or metal door?

At Automatic Door and Hardware all of our door closures include both hardware sets so you can install the door closure on a wood door such as an interior office door, or install it on a metal door such as a security steel door or aluminum storefront glass entrance door.

2. Identify Mounting Type

Door Closures can be mounted in 3 ways:
Top Jamb: Door Closure is mounted at the top of the door frame on the push side of the door.
Regular or Standard: Door Closure is mounted at the top of the door on the pull side of the door.
Parallel Arm: Door Closure mounts to the top of the door on the push side of the door.

At Automatic Door and Hardware all of our door closures come Tri-Packed, meaning they include all components so that the door closure can be mounted in any of the 3 configurations listed.

3. Identify Traffic Level At Door

Ask yourself how often is this door used? Is this a front entrance door into the building that gets alot of traffic? Or is this a storage room door, that is only use 10 to 20 times a day.

At Automatic Door and Hardware all of our door closures are ANSI/BHMA Grade 1, the highest door closure grade a manufacturer can achieve. This means that our door closures have been tested for over 2 million door cycles. With that being said, our door closures have well exceeded 2 million door cycles, however the door closure grading process uses the 2 million door cycle as the benchmark to qualify for a Grade 1. You can expect a life time of use out of our door closures. Grade 2 and 3 door closures are much lower grade door closures that have only been tested to pass lower door cycle counts. Door closures without a listed grade, are untested door closures for any amount of door cycles.

4. Identify Duty Cycle Needed

What kind of abuse does this door see. Is it a door that is vulnerable to vandalism such as a school entrance door? Or is it a restroom door in a calm, non-abusive environment?
