How to Pick the Right #Door Closer | #ESC_LLC #DoorCloser #DoorHardware #Security | One of the most difficult aspects of a door installation is selecting the right closer for the application. Most of the time it’s how the retractable arm mounts, including how and precisely where it’s to be mounted. https://wp.me/p97JNV-1QU
There are three basic methods in use (see photo above):
- Regular Arm
- Top Jamb
- Parallel Arm
Regular Arm: This method of door closure installation relies on a pull-side application where the closer uses a double lever arm. The arm assembly extends straight from the door frame. There are cases, however, where this door closure method can present a problem aesthetically, but it is the most efficient method for automatic door closure.
Top Jamb: This method of installation offers the most efficient means of automatic closure. It offers a superior means of door control where a door on an exterior wall swings to the outside of the structure it’s mounted to. Here, the door closer and arm assembly both project out from the door frame, similar to the Regular Arm mounting.
Parallel Arm: Of all three mounting methods, the Parallel Arm offers the most appealing appearance. With the door closed, there’s practically no hardware projecting from the frame for someone to tamper with. Thus, the parallel mounting method is the best one to use in vandalism-prone areas. It’s on the push side and so the arm assembly extends parallel to the door making it difficult for someone to tamper with. The parallel arm method also allows the door to swing 180 degrees. However, the arm is approximately 25% less power efficient than the regular arm or top lamb mounting methods.
