Degol : Types of door closers
The most common door closers in the market today are surface mounted, overhead concealed and floor mounted concealed. When choosing the best one for your application, consider these important factors:
location and type of opening
interior or exterior mounting
volume and frequency of door traffic
type of door
size and weight of door
wind or building pressure conditions.
Surface mounted door closers are most commonly used since they provide a wide range of features and options that aren’t found on other types of closers. They are available in four variations, including slide-track arm, regular arm surface mounted, parallel arm surface mounted and top jamb mounted. Surface mounted closers are commonly used for aluminum storefront doors and are the best option for low- to-medium traffic entrances. They are also highly economical and fairly easy to install, requiring a minimum of drilling or cutting.
Overhead concealed door closers are best used in medium-to-heavy traffic areas. They are installed and hidden from view inside the headers of storefront doors and frames. Overhead concealed closers can be positioned in center-hung or offset arm positions with narrow, medium, or wide stile doors.
Floor mounted door closers are the most durable, longest lasting option and are necessary when dealing with heavy doors or areas with high to extreme traffic. These high efficiency closers can be easily adjusted and work best in conjunction with tall, wide or substantial storefront doors, especially those made of insulating or heavy glass. Both floor mounted and overhead concealed door closers are always the best option when using all-glass rail or patch-fitted doors, as they offer improved aesthetics with minimal visible hardware. Furthermore, these all-glass applications lack practical mounting options for surface mounted closers.
