Door Closer Drop Plate Application Guide


Parallel arm closers are aptly named for how the arms sit parallel against the face of the door when the door is closed. The arms attach to the door on the frame and on the spindle of the door closer body. These types of door closers are popular in schools and other commercial properties because the arm is tucked in and is less likely to be misused or vandalized.	Also known as Standard Arm. This option is the most power-efficient option available, although it’s also the least attractive. The closer is a pull-side application that is located on the exterior of the door. There are two arms that connect together in this mounting style, one piece attaches to the frame, and the other piece attaches to a piston on the door closer body. These two arm pieces either screw or slide together. When the door is closed, the arm projects out perpendicular to the door.	Also known as Top Jamb. Essentially, these door closers are regular arm closers turned upside down. Like regular arm closers, top hinge closers have arms that have perpendicular projection out from the door. The difference is that the door closer body is mounted to the face of the door frame, not the door. Top jamb doors are commonly used for storefront doors as well as aluminum or glass doors, because these doors have narrow top rails. Top hinge closers are nearly as power efficient as regular arm closers.
