Common Types of Door Closers
The first door closer was created by Mr. L. C. Norton for the Boston Trinity Church in 1877 when the rector of the church lost his patience with a slamming door interrupting services. Today door closers are used in majority of commercial buildings. Door closers are required for fire-rated doors to help prevent the spread of smoke by keeping the door closed. In this article we will cover the basic mounting options and the most common types of closers in the industry.
3 basic types of mounting:
Regular arm mount: This type of device is mounted on the pull side of door and the arm is mounted to the header.
Top Jamb Mount: The device is mounted on the header and on the push side of the opening.
Parallel arm mount: This device is mounted on the push side of the door and the arm is mounted on either the rabbet or soffit of the frame.

These closers come in 105 or 90 degree opening which is basically where you want the door to stop. They can come in hold open or non-hold open options.
Code requirements for door closers
A couple code requirements to point out is your closing speed and opening force. These are driven by your ADA requirements. You must make sure you adhere to these things so that everyone is able to get in the doors correctly. When adjusting your closer you must make sure you adhere to the code requirements.
Closing Speed – Door Closers must be adjusted so that It takes at least five seconds for the door to move from an open position of 90 degrees to 12 degrees from the latch.
Opening Force – The accessibility standards require interior hinged, sliding, or folding doors, other than fire doors, to be opened with five pounds of force, maximum.
Floor concealed Closer
These types of closers are common in historical building or arch doors where there isn’t a way to mount a standard overhead closer. These closers are mounted on the floor and are going to be basically invisible to you and the door is going to pivot on the spindle of that closer and close the door like any regular surface mount or overhead concealed door closer.
