Step 1: Identify the Adjusting Screws

Locate the adjusting screws on your Norton door closer. These screws are usually labeled and can be found on the closer body or arm. The most common screws to look for are the closing speed screw, latching speed screw, and backcheck screw.

Step 2: Adjusting the Closing Speed

Turn the closing speed lever clockwise to increase the speed and counterclockwise to lower the speed. Make minimal changes and test the door after each one to confirm that the desired speed is obtained. It is critical to strike the proper balance so that the door does not close too rapidly or too slowly.

Step 3: Adjusting the Latching Speed

The latching speed controls how quickly the door closes in the last minutes before closing. Locate the closing speed screw and spin it clockwise to raise the speed or counterclockwise to lower the speed. Again, make slow modifications and test the door until the required latching speed is achieved.

Step 4: Adjusting the Backcheck

The backcheck feature prevents the door from opening too forcefully and damaging the surrounding walls or hardware. To adjust the backcheck, locate the backcheck screw and turn it clockwise to increase the resistance or counterclockwise to decrease it. Test the door to ensure it provides the desired backcheck effect.

Step 5: Testing and Fine-Tuning

After adjusting each component, test the door to evaluate its performance. Check for smooth closing, appropriate speed, and proper latching. If necessary, make further adjustments to achieve optimal results. Take your time during this process and be patient to achieve the desired door functionality.

Troubleshooting Common Issues

Sometimes, despite adjusting the Norton door closer, certain issues may persist. Here are some troubleshooting tips for common problems:

  • If the door slams shut suddenly, adjust the closing speed screw to slow down the closing action.
  • If the door doesn't close fully, adjust the latching speed screw to ensure a complete latch.
  • If you face other issues or difficulties, consult the norton door closer manual or contact a professional for assistance.
