- Regular / Standard Arm Closers: These are most power efficient and can be used anywhere. It is a pull side application in which it is located on the exterior of the door. It has two arms, in which one is attached to the frame and the other is attached to a spring – loaded box on the pull side of the door. When you close the door then the arms will project perpendicularly to the door.
- Top Jamb Closers: These are often used for glass storefront and aluminium doors why because these doors are having narrow top rails. The spring loaded box is mounted on the face of the doorframe in which the arms project out from the door perpendicularly.
- Parallel Arm Closers: These are most commonly used in places like schools and commercial properties. The two arms sit on the top of the door when closed. They are attached to the door using a spring loaded box that sits at the top of the push side of the door. This parallel arm is less power efficient when compared with other overhead options.
- Track Arm Mount: This mount has a roller that comes along with a metal channel track whenever the door closes and opens. It has pull or push side opening in which the closer body is mounted to the door’s face in both the cases. For pull side mounting, the track is mounted to the face of the head’s frame whereas the push side, the track is mounted to the soffit of the head’s frame.

Things to Consider Before Buying Automatic Door Closers:
Consider the following factors in order for you to end up with the best automatic door closer.
It is the crucial factor in closing a door in which it ranges in sizes 1 to 6 (1 applying the lightest closing force and 6 uses the strongest closing force). In general, interior doors will require spring size 3 while the exterior doors uses size 4 – 5 so that it will close against any negative pressures like wind.

For example if the door has extremely narrow frame, then you have to consider a concealed door closer. The heavier doors requires a closer that has large power size for optimal performance.
8. Closing Force / Power Size
Generally, the larger and heavier doors require more force to close or control them. So, you should consider the power size along with the maximum door weight and its width to determine the amount of closer force required for this automatic door closer.
- For power size 1, the maximum door weight should be 20 kg and maximum door width will be 750 mm.
- For power size 2, the maximum door weight will be 40 kg and the maximum door width is 850 mm.
- For power size 3, the door weight will be 60 kg and the door width is 950 mm.
- For power size 4, the max door weight will be 80 kg and the max. door width is 1100 mm.
- For power size 5, the max door weight is 100 kg and the max door width is 1250 mm
- For power size 6, the max door weight is 120 kg and the door width is 1400 mm.
The door controls are available either adjustable or fixed strengths to cater for the weight and size variation of different doors. If a door closer has a fire door then you have to fit a size 3. However, some types of door closers are adjustable and can vary their strength. This is convenient where the uncertain size required and facilitates a great adjustment ranges at fitting time.
9. Type of mounting

The door closers with an adjustable latching speed will allow adjustment of the closing speed for the final few degrees of closing. Simply, they set to either slow down or speed up for those final few inches.
Backcheck will slow the door in the opening swing which helps to keep it from hitting an adjacent wall. This feature will prevent the door from being suddenly thrown or opened either by the wind or people and thereby prevent the damage to the frame, door or its hardware.

- For low usage category, it can be up to 10,000 cycles per year
- For medium category, it will range from 10,000 to 100,000 cycles per year
- For high category, it will range from 100,000 to 500,000 cycles per year.
Also, you need to consider the needs of the users like some people like elders or less abled people may need some time to pass through the door, so need delayed close (frequency traffic). The places like schools, hospitals or shopping centres are considered as high volume usage.

American Disability Act (ADA) Reduced Opening Force – As per the ADA, you have to examine that the maximum opening force restrictions before buying the automatic door closer. In some cases, manufacturer’s print some disclaimer which states that ADA recommended force range may not be quite enough to close this automatic door closer.
The latch zone is the area that covers last few inches before the door gets hit its latch point. Generally, the latch speed valve is used to control the closing zone. Always remember that the latch speed of door closer which is properly adjusted will not slam the door closed by creating stress on the door and its frame.
A sweep speed (or door closing speed) is the time frame from the start of the door closing to a couple inches before the door hit the latch point. Whereas the last few inches of closing are controlled with the latch speed valve.
The overhead door closers are installed in 3 methods – parallel arm mounted, top jamb, and regular arm (standard). If a door closer comes with the hardware for all these 3 mounting methods then it is known as tri-packed door closer.
In each type of mounting, there are some pros and cons in which you have to decide which one is most suitable for your requirement.
Regular Arm – This application has the most power efficient and it is on pull side of the door where the double lever arm is used. Although, this arm assembly projects directly out from the door frame but this type of mounting has aesthetic issues.
Top Jamb – This is the best replacement for regular arm mounting why because it has become the best door closure for the doors in the exterior walls which swings out of the building.
Parallel Arm – It will provide the most pleasant appearance for an overhead surface closer that has a double lever arm. It is push side application of the door and the assembled arm will extend almost parallel to the door. You will find a little hardware that projects from the frame face when the door is closed. This application allows to swing the door at 180 degrees. It is 25% less power efficient than top jamb mounting or regular arm, as per geometry of the arm.
