Door Closers are available in various styles and sizes to suit a wide range of applications. They can be fitted to standard or fire rated doors and can also be adjusted to fit your specific needs.
A commercial door closer is a mechanical device that uses the compression force of an internal spring and hydraulics to automatically close a door when it is opened. They are a popular choice for high traffic locations such as schools, shopping centers, and offices.
It is important to note that all closers are subject to wear and tear through the years and will need to be regularly maintained and adjusted. This includes ensuring that all hinges are in good working order, the door frame is free from defects, and that the weatherstripping around the closer is in good condition.
UL Door Closer is an automatic door closing device that can be installed on both fire rated and non-fire rated doors. It provides smooth operation and durability in both commercial and residential environments.
Designed to handle medium to heavy traffic in high traffic commercial entrances, this door closer is perfect for restaurants, schools, hotels, hospitals, shopping malls and other public areas. It also helps to prevent slams that can lead to accidents, injuries and loss of property.
Easy to install, this safety spring-activated door closer has a surface-mounted design that makes it easy to attach to a push-side door. It is a single-sided device that can be adjusted to close doors weighing up to 150 lbs. It is available in a satin chrome finish and U.L. listed with a 1/2 hour fire rating.
When selecting a closer for high-traffic doors, choose ones that have been tested to perform under Grade 1, which is for entryways that experience a high level of traffic and frequent stress. In addition, a Grade 1 closer should be able to withstand wind pressure and stack forces.
For high abuse applications, look for a closer that has been tested to withstand 300-pound hang tests and that offers relief valves and oil bypass ports. These features minimize the amount of abuse that door frames and closers take, says Pen.
The closer should also have a hold open feature. This allows managers to set the door to a "hold" position in case of a power failure, so that it will still close.
A Commercial Door Closer is a mechanical device that closes doors after they are opened. They have internal springs & hydraulic oil with cylinders and valves that adjust the speed of the door closing and latching.
They come in many different styles depending on the application and circumstances at the opening. Modern style surface mount closers have become the most popular due to their ease of use and maintenance.
Floor closers are used when there is no room to install a surface mount closer or where aesthetics are important. They have the added advantage of controlling much heavier doors since they are mounted in the floor.
The closer body contains a rack and pinion design with a tempered steel spring inside the body. As the door is closed, the rack and pinion moves the tempered steel spring and compresses it.
All commercial door closers have an advance flowing synthetic hydraulic fluid which helps lubricate the internal gears and spring. It also provides speed regulation and control of the door closer in all weather conditions.
Back-Check – This option is optional on some commercial door closers and is designed to help prevent the door from opening too quickly and hitting stationary objects. This feature is controlled by a small screw labeled with an “L.” Turning this screw clockwise increases the pressure that is needed to open the door, while turning it counterclockwise reduces the pressure required to open the door.
Adjusting a commercial door closer is not for everyone, as it requires specialized knowledge and equipment. However, it is a good idea to learn the basics and be able to make adjustments to your commercial door closer when necessary.
