What are Door Closers?

Door closers are mechanical devices that close a door in a controlled manner, preventing it from slamming. Door closers are often used for safety and security reasons, such as preventing fire spread, controlling noise, and maintaining privacy. Door closers can be surface-applied or concealed, and they can have different features such as adjustable closing speed, backcheck, delayed action and hold-open.

What are Door Closers Parts?

  • Arm: The part that connects the door closer body to the door or the frame and controls the opening and closing motion of the door.
  • Body: The part that contains the spring and the hydraulic fluid that regulate the closing force and speed of the door.
  • Cylinder: The part that houses the piston and the valve that control the flow of hydraulic fluid in the body.
  • Cover: The part that covers and protects the body and the cylinder from dust and damage.
  • Bracket: The part that attaches the arm or the body to the door or the frame.
  • Plate: The part that allows for different mounting options and hole patterns for the door closer.
  • Spindle: The part that connects the cylinder to the arm and transfers the closing force to the door.
  • Pinion: The part that rotates inside the cylinder and drives the piston.
  • Piston: The part that moves inside the cylinder and creates pressure on the hydraulic fluid.
  • Valve: The part that adjusts the flow of hydraulic fluid and regulates the closing speed and latching speed of the door.
How to install a Door Closer?

  • Identify the door-swing direction and choose the appropriate mounting option for your door closer (parallel arm, regular arm or top jamb).
  • Mark the drilling locations on the door and the frame using a template or a ruler and a level.
  • Drill pilot holes on the marked locations using a drill bit suitable for your door material (wood or metal).
  • Install the door closer body on the door using screws and washers. Make sure the body is aligned with the holes and level with the door edge.
  • Install the swingarm bracket on the frame using screws and washers. Make sure the bracket is aligned with the holes and level with the frame edge.
  • Attach the swingarm to the closer body and the bracket using pins and clips. Adjust the arm length if needed.
  • Test the door closer by opening and closing the door several times. Adjust the closing speed, latching speed, backcheck and hold-open features if your door has them closer. Refer to your door closer manual for specific instructions on how to adjust these settings.
