Door closers close doors automatically when a person enters or goes out of a premises. These structures are already available in many of the establishments anywhere. However, they might be commonly found anywhere but most people fail to notice them. They are normally found on doors used as main entrance/exit doors in any building. They are also used in some important inside doors such as kitchens, fire exits, toilet doors, etc. Door closers are used not only to secure places, but they are also used to maintain the temperature inside the building. In choosing a door closer, it is important to look into some factors such as door size, door functions, door traffic and the types of door (internal or external door).
If the doors are not always used, non-heavy duty closed doors can be used. This means that the traffic of the doors is very limited. Non-heavy duty door closers are available in interior and exterior doors applications. They also suit bests to restroom doors because they can be used for door with a height of 4 feet. But they can also be adjusted to fit a five feet door.
Any main entrance/exit doors which are busy should be installed with moderately heavy or heavy door closers. In selecting the door closers of these magnitudes, remember that moderately heavy-duty door closers only fit with door size of 3 feet to 4 feet. Whereas the heady duty door closers fit well with door sizes of 4 feet and 6 inches (interior door) and 3 feet and 6 inches (exterior door). In any case, also remember to buy only the certified items under ANSI standard A156.4, grade one.
Above all other doors, fire exit doors should be fitted with heavy-duty door closers. Heavy-duty structures are essential for them to withstand extreme traffic during emergencies. Examples of these door structures are the UL and cUL listed. There are also special types of door closers that are very useful during fire emergencies. They are designed with electric sensor that permanently opens the door until the fire problem let-off the device that allows the door to close. It is again essential that these items comply with NFPA 101 safety standards.
When installing door closers in your business buildings, use the ADA approved products to avoid problems in the future. An example of this door closer is the auto-equalizer type. This is not only ideal for disabled and elderly people; it also uses less power to operate. You can also choose the design that opens automatically. Thus, to comply with the regulations, look for closers that comply with ANSI A156.19 provisions and are UL 325 compliant.
Lastly, door closers also come in different makes. Some are made from bronze, brass or aluminium. Whatever metal you like, you can always have the types that can be used with busy or non busy doors. Their prices can also vary from $140 to $2000 depending on the type of the door closer you want.
