The regular arm is used on the “pull” side of the door. This is power-efficient but can be less attractive because the arm projects out.
A top jamb is also power-efficient and projects out from the “push” side of the door. While a regular arm is mounted on the door, the top jamb is mounted on the doorframe, which is useful for doors with narrow top rails, such as commercial glass entry doors.
The parallel arm is more attractive than the other two options because it is not perpendicular, which also makes it more difficult to vandalize. It is more common for these reasons, but less powerful.
Shopping for Automatic Door Closers
Before purchasing an automatic door closer, determine whether the closer will be mounted on the pull or push side. Note the door material if the closer will be mounted on the door itself. The size of the location also matters if it will be placed above the door.
Measure the door width, size and weight. It’s also important to note if the closer is for an interior or exterior door, if it’s in a high-traffic area and how much “backswing” the door needs.
Depending on the answers to these questions, you may need a heavy-duty door closer for high-traffic areas.
