Overhead Concealed Closers

Arm Loosening

 

Make sure Arm is tight on Spindle

Symptoms of Loose Arm:

Door will not fully close. Door will slam just before closing. Door will have little or no control in latch speed range. Door will “bounce” back after closing against frame.


Offset Application

 

 

 

Center Hung Application

 

 

It is important that the screws be tightened at the same time; not one fully and then the other. This will cause the arm to wobble on the spindle shortening the life of the installation and the arm.


Also – Insure arm alignment screws are secure on the end load application.
