How does the hold-open function work?
Hello Michael, thank you for your question. In general terms, a manual door closer is designed to assist a person using a doorway allowing them to smoothly and effectively open and shut a door without the need to physically return the door to the framed opening themselves. When properly adjusted, there will be a slight "back-pressure", giving the user some feedback as to the weight of the door, followed by a smooth transition as the door glides easily open in front of the user. Upon reaching the maximum set opening of the door, the closer takes full control dampening the opening forces, quietly and gently closing the door until the door is back in the frame, latched and ready for the next use. In every door closer application, the one basic essential requirement is that the door closer body and door closer arm be properly and securely attached to the doorway components. A door closer body and arm operate the opening and closing actions of the door that they are mounted to, exerting forces that are controlled by a few different methods. Some closers operate using spring tensions while others operate using air pistons. The most elaborate and sophisticated closers function using both spring tension.
