How To Adjust Door Closer

Door Closer

Adjusting a door closer might seem daunting, but with the proper guidance, it can be a straightforward process. Door closers are essential for ensuring controlled and smooth closing of doors, particularly in commercial settings or buildings with heavy foot traffic.

Whether the door closer needs fine-tuning due to speed, force, or alignment issues, here’s a step-by-step guide on how to adjust it effectively:

Tools You Might Need:

  • Screwdriver (typically a flathead or Phillips)
  • Allen wrench (depending on the closer model)
  • Lubricant (optional for smoother operation)

Adjusting Door Closer Speed and Closing Force:

1) Identify Closer Controls:

  • Locate the adjustment screws or valves on the door closer. These are usually located at the closer’s end or closer to the hinge.

2) Adjusting Closing Speed:

  • To slow down the closing speed: Turn the screw or valve labelled “Speed” or “Closing Speed” clockwise. This regulates the hydraulic fluid flow, slowing down the closing speed.
  • To increase the closing speed: Turn the screw counterclockwise.

3) Setting Closing Force:

  • To decrease the closing force: Turn the adjustment screw clockwise. This reduces the force exerted by the closer.
  • To increase the closing force: Turn the screw counterclockwise.

Alignment Adjustments:

1) Check Alignment:

  • Ensure the door is aligned correctly and closes evenly. Adjustments are needed if it’s dragging on one side or not closing evenly.

2) Adjusting Latch Speed (Optional):

  • Some closers have a separate adjustment for latch speed, allowing adjustments to the final few inches of the door closing. Follow similar steps as adjusting the closing speed.

Step-by-Step Adjustment Process:

1) Prepare the Door Closer:

  • Please open the door fully and prop it open using a doorstop or wedge to access the closer mechanism easily.

2) Use Caution:

  • Before adjusting, take note of the current settings and make small, incremental changes to prevent over-adjustment, which can affect the door’s performance.

3) Begin Adjustment:

  • Using the appropriate tool, turn the adjustment screws gradually while observing the changes in the door’s closing speed and force.

4) Test the Door:

  • After each adjustment, close and open the door multiple times to ensure it functions smoothly and evenly.

5) Fine-Tune as Needed:

  • Continue making slight adjustments until the door operates as desired, closing smoothly without slamming or being too slow.

6) Lubricate (Optional):

  • If needed, apply lubricant to hinges, pivot points, and moving parts to ensure smoother operation.

Safety Precautions:

  • Exercise caution when adjusting the door closer to prevent injury, especially with heavy doors or spring-loaded closers.
  • Work in a well-lit area and ensure a stable footing while making adjustments.

By following these steps and being mindful of the door closer’s mechanism and adjustments, you can effectively fine-tune its settings to achieve the desired closing speed, force, and alignment.

If you need help with making adjustments, consider consulting a professional or the door closer’s manufacturer for guidance.
